(1)the anti-sniper hand detection system that the 3rd research institute of science and technology group of China Electronics releases is made up of 1-2 portable array antenna and signal processing unit.System receives light weapon firing and produces acoustic signals, and sniper is implemented to survey and location.
(2)" adder " anti-sniper hand infrared detection system has adopted audio frequency and 2 kinds of sensors of photoelectricity, can measure the orientation of sniper or small arms emissive source, pitch position distance, and the vision signal producing is sent to digital signal processor, extrapolate the residing position of sniper with this, orientation, pitching positioning precision is higher, this system is in the time that the upper detection probability of 2-3 times of distances of sniping gun range can reach 100%. work, thermal camera needn't aim at or close sniper, even if only need sight line can observe target. in the middle of sight line, there is the small-scale obstacle thing (as bushes), system still can detect information outward at effective striking distance of sniper, detection probability exceedes 95%. in addition, this system also can be mutually comprehensive with the antagonism emitter of remote control.
(3)muscovite " Portable Automatic photoelectronic warfare system ", in the detection phase, once laser beam scans gunsight, glasses or other optical lens, it just can reflect.Built-in sensor receives after the laser beam being reflected back, and this system just can start the groove information in the lens that detect and the boresight of gunsight to contrast.Sensor can be identified the laser beam of wavelength between 0.53-1.06 micron.
Above three kinds of technology, are easy to expose, and are not easy to investigation, and cost is more expensive simultaneously, can not be widely used.
Utility model content
The purpose of this utility model wants implement device simple in structure, lightweight, can fast, accurately find enemy sniper present position, for combatant provides precision strike target.
For this reason, the utility model provides a kind of anti-sniper hand optical system, comprise the Laser emission lens on the emitting light path that is arranged on Laser emission endovenous laser transmitter and is arranged on this generating laser, be arranged on the laser pickoff in laser pick-off chamber, its special character is, described generating laser is that wavelength is the semiconductor laser of 808nm, and described Laser emission lens are made up of a single element lens and one group of balsaming lens, and group balsaming lens is placed between single element lens and generating laser;
Laser pickoff comprise be arranged on laser pick-off chamber prosopyle object lens, be placed in the eyepiece of laser pick-off chamber deutostoma, be placed in low-light array CCD, OLED high definition miniscope between object lens and eyepiece, low-light array CCD is placed between object lens and OLED high definition miniscope.
Above-mentioned eyepiece is arranged with a glance cover outward.
Above-mentioned objective aperture is 39mm, numerical aperture 2.9 mm.
Above-mentioned object lens are made up of a cemented doublet and the simple lens that is placed in this cemented doublet outside.
The anti-sniper that the utility model provides is surveyed optical devices and is adopted active detection optical system, design form is made up of generating laser and laser pickoff, laser adopts and the insensitive 808 wave band near-infrared lasers of human eye, guaranteeing that Emission Lasers and laser receiver system match in fixed transmission angle, also can guarantee the uniformity coefficient of laser beam energy, to reach the operating distance of total system.
Laser receiver system adopts the larger objective lens design of relative aperture, the security of simultaneously fighting for assurance system.System adopts OLED imaging and amplifies laggard pedestrian through eyepiece system and observe survey, reaches more satisfactory safety, concealed effect.
Below with reference to accompanying drawing, the utility model is described in further details.
Accompanying drawing explanation
Fig. 1 is the signal of anti-sniper hand optical system light path part.
In figure: 1, object lens; 2, low-light array CCD; 3, OLED high definition miniscope; 4, eyepiece; 5, Laser emission lens; 6, generating laser.
Embodiment
Figure 1 shows that the light path part schematic diagram of anti-sniper hand optical system, be not difficult to find out by this figure, this anti-sniper hand optical system comprises the Laser emission lens 5 on the emitting light path that is arranged on Laser emission endovenous laser transmitter and is arranged on this generating laser 6, be arranged on the laser pickoff in laser pick-off chamber, special character is, generating laser 6 is that wavelength is the semiconductor laser of 808nm, be that laser adopts and the insensitive wavelength of human eye is 808nm near-infrared laser, guaranteeing that Emission Lasers and laser receiver system match in fixed transmission angle, also can guarantee the uniformity coefficient of laser beam energy, to reach the operating distance of total system, not only reduce the cost of product, disguise and the security of doing wartime have been improved simultaneously.
Wherein, being uniformly distributed of particular transmission angle when guaranteeing Laser emission and light spot energy, Laser emission lens 5 have adopted collimation lens design form, carry out complete design by a monolithic and one group of balsaming lens, guaranteeing that Emission Lasers and laser receiver system match in fixed transmission angle, also can guarantee the uniformity coefficient of laser beam energy, to reach the operating distance of total system.
