Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The embodiment of the invention provides a novel laser electronic target, which comprises a bottom plate 1, wherein a front surface 2 of the bottom plate 1 is a diffuse reflection reflective surface, a plurality of light blocking material strips 3 protruding forwards are arranged on the front surface 2 of the bottom plate 1, the plurality of light blocking material strips 3 enclose a plurality of shooting areas 4 which are not communicated with each other, an optical fiber 5 is arranged in each shooting area 4, a light picking surface 6 and a light emitting surface 7 are arranged on the optical fiber 5 in each shooting area 4, different numbers of light picking surfaces 6 are arranged according to the size of the shooting areas 4, light reflected by the diffuse reflection reflective surface irradiated by a laser beam can be picked up by the light picking surfaces 6, the light emitting surface 7 of the optical fiber 5 in each shooting area 4 is connected with a photoelectric sensor 8, and the photoelectric sensors 8 are electrically connected to a processor.
When the laser gun is used, laser emitted by the simulation gun is a highly converged light beam, and the light beam irradiates the electronic target and is reflected by the front surface of the bottom plate after falling into a certain shooting area. Because the front surface of the bottom plate is a diffuse reflection surface, the laser beams which are highly converged are reflected and scattered to form light rays towards all directions, and the reflected light rays are picked up by the light pickup surface of the optical fiber and then enter the optical fiber from the light pickup surface. The light is transmitted to the light-emitting surface almost without damage in the optical fiber and is received by the photoelectric sensor, the processor can identify which photoelectric sensor receives the light signal, and then identify which shooting area is hit by the laser, and the target hitting score is determined. Simultaneously, the material strip of hindering light can prevent that light signal from getting into adjacent shooting region, avoids the shooting score to appear the confusion.
After the laser beam is scattered by diffuse reflection, the reflected light can form a larger light irradiation area. When the shooting area is small, the light irradiation area can be distributed over the whole shooting area, so that only one light pickup surface can be designed; and when the shooting area grow, this light irradiation area probably can not be covered with whole shooting area, consequently needs a plurality of light picking up faces of design in different positions to guarantee that reflected light can be picked up by the light picking up face, the area of shooting area is bigger, and the light picking up face that needs just more.
According to the invention, the laser beams are dispersed in a diffuse reflection mode on the front surface of the bottom plate, and are transmitted to the photoelectric sensor after being picked up by the optical fiber, and the laser electronic target in the prior art picks up the laser by the light guide plate, conducts the laser in the light guide plate of the whole shooting area and is received by the photoelectric sensor. Compared with the laser electronic target in the prior art, the laser electronic target adopts a new light transmission technology, does not need a light guide plate, can greatly reduce the weight and the cost of the laser electronic target, and is convenient to use and popularize and apply in a large range.
In addition, the optical signal is conducted through the optical fiber, the transmission of the optical fiber is almost lossless, and the optical signal picked up by the light pickup surface can be transmitted to the photoelectric sensor no matter where the light pickup surface is, so that only one photoelectric sensor is needed in one shooting area.
The invention is not limited by the material of the bottom plate, the material of the bottom plate can be selected from a wide range, such as ethylene-vinyl acetate copolymer (EVA), plastics and the like, and other common materials can also meet the requirements. The front surface of the bottom plate is a diffuse reflection reflecting surface, the formation of the surface does not make special process requirements, only needs diffuse reflection, and because the surfaces of the existing various materials are basically rough, the requirements of the invention on diffuse reflection can be met.
The invention does not limit the arrangement mode of the optical fiber light-picking surface, as long as the optical signal can be picked into the optical fiber, and the following specific examples are given:
example one:
in this example, as shown in fig. 1 to 4, the optical fiber 5 is a side optical fiber, the side surface of the side optical fiber is an optical pickup surface 6, and one or two end surfaces of the side optical fiber are light emitting surfaces 7.
The side light optical fiber is also called a whole body light-emitting optical fiber and consists of a core material and a skin material, wherein the refractive index of the core material is higher than that of the skin material, the core material mostly adopts transparent polymers or transparent organic matters, and the skin material generally adopts fluoroplastics, such as polytetrafluoroethylene and the like. Side-lit optical fibres are commonly used for lighting and decoration, and in use, light is emitted from one or both end faces of the side-lit optical fibre, and out the side, i.e. illuminated by side-lit illumination. Since light can enter from the end face of the side optical fiber and exit from the side face, the light can also enter from the side face of the side optical fiber and exit from the two end faces according to the principle that the light path is reversible.
The side surface of the side optical fiber is used as a light pickup surface, and the end surface is used as a light emitting surface to be connected with the photoelectric sensor.
The side-light optical fiber sheath is made of polytetrafluoroethylene material, and the sheath material has the characteristics of water repellency and oil repellency, so that the material is difficult to adhere to the sheath material, and is difficult to adhere and fix through an adhesive. In order to fix the sidelight optical fiber, the transparent sleeve 10 is arranged on the sidelight optical fiber in the present example, the transparent sleeve is in the form of a plastic tube or a heat-shrinkable tube, and the transparent sleeve is fixed on the bottom plate through an adhesive, so that the sidelight optical fiber can be fixed.
Example two:
in this example, as shown in fig. 1 to 4, the optical fiber 5 is a side optical fiber, the side optical fiber is provided with a notch 9, the side surface of the side optical fiber and the notch surface at the notch are light pickup surfaces, and one or two end surfaces of the side optical fiber are light exit surfaces.
In the first example, the side surface of the side optical fiber is used as a light-collecting surface, which can achieve the purpose of collecting optical signals. However, after the laser beam is scattered by diffuse reflection, the intensity of the laser beam is inevitably reduced, and although the side surface of the side optical fiber can also pick up light, the light-picking capacity of the side surface of the side optical fiber is poorer than that of the end surface of the side optical fiber (not only the side optical fiber, but also other types of optical fibers are the strongest in the light-picking capacity of the end surface, and some types of optical fibers have opaque skin layers, and the side surface does not have the light-picking capacity).
Therefore, if an optical signal whose intensity is reduced after diffuse reflection is picked up only by the side surface (optical pickup capability is inferior to the end surface) of the side optical fiber, the optical signal may not be picked up or may be weak.
In order to solve the above problem, the present example provides a notch 9 on the side optical fiber, where the side optical fiber is cut by a cutter, but a part of material is not cut from the side optical fiber, and after cutting, if no pulling force is applied to the two sides of the notch of the side optical fiber, the two notch surfaces of the notch are still attached together. The notch surface at the notch is equivalent to the end surface of the side optical fiber, and the notch surface as a light pickup surface can well pick up optical signals. This example is equivalent to artificially increasing the end face on the side optical fiber to improve the optical pickup effect.
In this example, the notch surface formed by the notch may be disposed perpendicular to the axis of the side optical fiber, or may be disposed obliquely to the axis of the side optical fiber, and both the perpendicular and oblique arrangements may pick up the optical signal.
When optical signals are transmitted in the optical fibers, a part of the optical signals can be lost on the two notches at the notches (because of the refraction and reflection of the two notch surfaces), in order to prevent the optical signals from being lost greatly, the side optical fibers can not be cut off at the notches when the notches are cut off, the uncut part is used for transmitting the optical signals in the optical fibers, the loss of the optical signals can be reduced, and the uncut part also plays a role in connection, so that one side optical fiber is still a whole.
The fixing manner of the side optical fiber of the present example is similar to that of the first example, and the difference is only that the transparent sleeve 10 is arranged at the notch of the side optical fiber in the present example, so that the side optical fiber can be fixed through the transparent sleeve, the notch can be enabled not to deform, two notch surfaces at the notch can be attached together or the gap between the two notch surfaces is small, and the transparent sleeve does not obstruct the optical signal from entering the notch surface.
Transparent binder material can be filled in the cut, so that the two cut surfaces at the cut are firmly connected, and the filled transparent binder material ensures that the cut has no air medium, thus reducing the loss of optical signals at the cut (because the boundary between the air medium and the cut surface has large loss of the optical signals, and the boundary between the solidified solid transparent binder material and the cut surface has small loss of the optical signals). Of course, the transparent adhesive material may not be filled and does not affect the practice of the present invention.
When the adhesive material is filled, the sidelight optical fibers can be completely cut off at the notch, so that the connection at the notch is ensured through the adhesive, the auxiliary connection is carried out through the transparent sleeve, and the adhesive can also ensure that the optical signals are not greatly lost when being transmitted at the notch.
Example three:
in this example, the optical fiber is a side optical fiber, the side optical fiber is provided with a notch, the side surface of the side optical fiber and the notch surface at the notch are light pickup surfaces, and one or two end surfaces of the side optical fiber are light emitting surfaces.
The difference between this example and the second example is that in this example, a notch is formed in the side optical fiber, and the notch is a notch such as a V-shaped notch formed by cutting a part of the side optical fiber with a cutter. The other parts are the same as those in the second example, and are not described again in this example.
Example four:
in this example, as shown in fig. 6, the optical fiber is an optical fiber bundle 11 formed by densely arranging a plurality of optical fiber units, an end face formed by aligning one ends of all the optical fiber units in the optical fiber bundle 11 serves as a light emitting face 7, an end face of the other ends of all the optical fiber units in the optical fiber bundle serves as a light collecting face 6, and lengths of all the optical fiber units in the optical fiber bundle are not all equal.
Since the optical fiber units are unequal in length and have one end aligned, the other ends (light-pickup faces) of the plurality of optical fiber units are distributed at different positions in the shooting area, so that optical signals can be picked up even at different positions.
Example five:
the optical fiber of this example is a common optical fiber, a notch is formed in the optical fiber, a notch surface at the notch is an optical pickup surface, and one or two end surfaces of the optical fiber are light emitting surfaces.
This example is similar to example two, except that the optical fiber of this example is a regular optical fiber, not a side optical fiber, and correspondingly, the notch surface of the optical fiber is an optical pickup surface and the side surface of the optical fiber is not an optical pickup surface in this example. Except for the differences, the present example is the same as example two, and specific statements refer to example two.
Example six:
the optical fiber of this example is ordinary optical fiber, has seted up the breach on the optical fiber, and the breach face of breach department is the light pick-up face, and one or two terminal surfaces of optical fiber are the plain noodles.
This example is similar to example three, except that the optical fiber of this example is a plain fiber. In addition to the differences described above, this example is the same as example three, and specific statements are made with reference to example three.
The foregoing examples one to six merely exemplify the optical fiber and the light-collecting surface and the light-emitting surface thereof, but are not limited to the above four forms.
As an improvement of the embodiment of the invention, the novel laser electronic target further comprises a light-transmitting front coating 12, the front coating is arranged on the front side of the light-blocking material strips 3 and the optical fibers 4, the front coating 12 has a light filtering function, and the front surface of the front coating 12 is provided with a shooting indication mark 13.
In theory, the laser spot irradiated on the electron target is in a standard circular shape, but in practice, the laser spot is not in a standard circular shape due to the influence of the processing technology of the laser emitter, pollution to the front end of the laser emitter and the like. For example, the middle of the laser spot is a standard or approximately circular area, and a certain halo or stray spot is arranged around the laser spot, and the halo or stray spot causes the whole laser spot to be relatively large. When the laser spot in the form is shot to the edge of the shot area, the halo or the stray spot is likely to irradiate into the adjacent shot area, so that the halo or the stray spot is received by the photoelectric sensor of the adjacent shot area, and the false report of the target hitting result is caused.
Therefore, the front coating is arranged on the front side, the front coating has a light filtering function, for example, the front coating can be a light filtering film, the light intensity of the laser is attenuated by the light filtering film, the light intensity of the halo or the stray spots is lower than that of the centers of the light spots, so the halo or the stray spots can be completely attenuated (or attenuated to the extent that the photo sensor cannot receive the halo or the stray spots), although the centers of the light spots are also attenuated, the centers of the light spots can still be identified by the photo sensor, and the defect of false target achievement caused by irregular laser light spots is overcome.
The laser of the laser simulated shooting system can be coded laser and non-coded laser, when the coded laser is used, the photoelectric sensor judges whether the laser is received or not through coding, and when the non-coded laser is used, the photoelectric sensor judges whether the laser is received or not through light intensity. Therefore, when the laser is not coded laser, the ambient light can generate certain interference on the photoelectric sensor, and if the ambient light reaches certain intensity, the ambient light can be received by the photoelectric sensor, so that the false report of the target achievement is caused. The filter film can also play a certain role in filtering ambient light, so that false alarm is further prevented.
In the case of shooting, it is necessary to give instructions to the shot region, for example, to define each target ring, and therefore, the front coating film of the present invention may be provided with a shooting instruction mark 13. The shooting indication mark can be directly drawn on the front surface of the front covering film, and the shooting indication mark can also be an independent film structure, for example, the shooting indication mark can be a mesh paste, and the front surface of the mesh paste is provided with a pattern for indicating shooting. The single-layer shooting indication mark can also play a certain role in eliminating laser halo or stray spots and filtering ambient light.
As described above, the outer jacket material of the side optical fiber is a hydrophobic and oleophobic material, and is not easily fixed by a fixing means such as an adhesive. In order to fix and mount the end face (light emitting face) of the side optical fiber, the invention is provided with a mounting seat on the bottom plate, as shown in fig. 5, the mounting seat comprises an upper cover 14 and a lower cover 15, the light emitting face 7 of the optical fiber 5 is tightly embedded in the upper cover 14, the photoelectric sensor 8 is mounted in the lower cover 15, the upper cover 14 is fastened in the lower cover 15, the light emitting face 7 of the optical fiber 5 is aligned with the receiving head of the photoelectric sensor 8, and the lower cover 15 is fixed on the bottom plate 1 through screws.
The end face of the side optical fiber is fixed by the mounting seat and the photoelectric sensor is mounted, so that the problem that the end face of the side optical fiber is difficult to fix is solved, and the fixing mode is simple and reliable. This fixing may be used not only to fix the side-light fibres but also to fix other forms of fibres, for example the aforementioned fibre bundles.
The installation seat can be located in a groove on the front surface of the bottom plate 1, or can be located in a groove on the rear surface of the bottom plate 1, and when the installation seat is located on the rear surface, the optical fiber 5 penetrates through a through hole in the bottom plate to be connected with the installation seat.
The laser is reflected when it strikes an object, and the reflected laser is generally not strong enough to trigger the photosensor. However, if the reflected laser light just irradiates the vicinity of the photoelectric sensor, the photoelectric sensor is easy to be triggered, and false alarm occurs, so the mounting seat is arranged in the groove on the rear surface of the bottom plate, and the photoelectric sensor is also positioned on the back surface of the bottom plate, so that the interference of the reflected light can be prevented.
The laser electronic target of the invention can be made into any shape according to the requirement, as one example, as shown in fig. 1, the novel laser electronic target is an annular target, the shooting area 4 is annular, and the optical fiber 5 is arranged in the shooting area 4 in a circular or circular arc shape at the radial middle position of the shooting area 4; the arrangement mode enables the optical fiber to conveniently receive the optical signals in the shooting area, the distance between each point in the shooting area and the optical fiber is short, the distance between each point in the shooting area and the light pickup surface is short, and the loss of the optical signals can be reduced.
Or, as another example, as shown in fig. 2, the novel laser electronic target is a chest ring target, the shooting area 4 is annular or partially annular, and the optical fiber 5 is arranged in the shooting area 4 in a circular or circular arc shape at the radial middle position of the shooting area 4; the benefits of such an arrangement are similar to those of an annular target.
In order to facilitate the arrangement of the optical fibers, it is common to make the optical fibers 5 circular as much as possible, and a part of the optical fibers 5 is located outside the effective area of the chest ring target, and to prevent the interference of the optical fibers with the light, a light shielding material 16 is disposed to shield the part, as shown in fig. 2.
In order to facilitate the fixation, the laser electronic target can also comprise a rear mounting plate, the rear mounting plate is arranged on the back surface of the bottom plate, all the photoelectric sensors are arranged on a strip-shaped circuit board, a circuit board groove is formed in the rear mounting plate, and the circuit board is arranged in the circuit board groove; and fixed frames are arranged around the side surfaces of the bottom plate and the rear mounting plate.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the appended claims.
