Abstract
The utility model relates to an optical-fiber door bottom speculum including a glass optical-fiber image transmission rod, an object lens, a rectangular prism, an audio collector, infrared lighting devices, an image eyepiece set, a video collector and a display; the front end of the glass optical-fiber image transmission rod is provided with the object lens; the object lens is provided with the rectangular prism; the audio collector and the infrared lighting devices are arranged at the two sides of the rectangular prism; the rear end of the glass optical-fiber image transmission rod is connected with the imaging eyepiece set which is arranged on the video collector; and the video collector is connected with the display. The beneficial advantages of the optical-fiber door bottom speculum are: the rectangular lens is installed at the front part of the object lens so that 360-degree comprehensive observation is realized; integrated transmission of audio signals and video signals is realized; and the infrared lighting devices and a digital high-definition low-light-level image sensor are adopted in a dark environment for real-time monitoring so that the collected images are clear.
Description
Technical field
The utility model relates to safety check investigation field, is specifically related to sight glass at the bottom of a kind of optical fiber door.
Background technology
Endoscope can extend in narrow space or the slit and observe because it has flexible probe, obtains internal image, so endoscope is widely used in fields such as clinical medicine, industry detection, case investigation.
Endoscope is a pipe that is equipped with light, and it can enter in the body in the oral cavity enters stomach or through other natural ducts, utilize endoscope to see the pathology that X ray can not show, so it is very useful to the doctor.For example, by endoscope, the doctor can see ulcer or the tumour in the stomach, makes best therapeutic scheme accordingly.At present, endoscope mainly has two kinds of results, and a kind of is the hard tube formula, and another kind is hose type, though the hard tube formula is simple in structure, image quality is poor, and the hose type phenomenon is effective, but the price height.
Application number is that 200710018533.2 patent of invention discloses a kind of snake-shaped wireless electronic endoscope, adopt wireless signal transceiver to receive picture signal, avoided causing because of signal cable line fault the problem of operating difficulties, application number is that 200610126495.8 patent of invention discloses a kind of fujinon electronic video endoscope, and this invention better becomes the camera head of fujinon electronic video endoscope the camera head of different size.
Fujinon electronic video endoscope is typically equipped with illuminator, works under the condition of dark.Visible illumination is generally adopted in the illumination of fujinon electronic video endoscope at present, and light source is the light emitting diode of metal halide lamp or high light.In some special application scenarios, be not suitable for adopting visible illumination, if adopt visible illumination when carrying out secret investigation, be found easily to give away one's position, so the fujinon electronic video endoscope of visible illumination can not satisfy some special application demands.
At present, fibre opic endoscope all adopts thin diameter endoscope to monitor, its direction of observation can only be looked at straight, can not the transmission of audio signal when carrying out video signal transmission, fibre opic endoscope adopts quartzy coherent fiber bundle to transmit the signal that collects, and optical fiber must enough can guarantee to gather clear picture by force, and the manufacturing cost height is of limited application.
The utility model content
The purpose of this utility model overcomes deficiency of the prior art exactly, propose a kind of multi-faceted, adopt glass optical fiber to pass the picture rod, integrate sight glass at the bottom of the optical fiber door of sound signal and vision signal.
Sight glass at the bottom of a kind of optical fiber door described in the utility model, comprise that glass optical fiber passes picture rod, object lens, right-angle prism, audio collecting device, infrared illuminator, imaging eyepiece group, video collector, display, described glass optical fiber passes and is provided with object lens as nose, described object lens are provided with right-angle prism, described right-angle prism both sides are provided with audio collecting device and infrared illuminator, described glass optical fiber passes as excellent rear end and connects into picture eyepiece group, described imaging eyepiece group is arranged on the video collector, and described video collector is connected with display.
Be preferably, described video collector is digital high-definition twilight image sensor.
Be preferably, when described glass optical fiber passed and connects into picture eyepiece group as excellent rear end, described glass optical fiber passed as the bending of excellent rear end, and angle of bend θ is in 120 °＜θ＜180 °.
Be preferably, described angle of bend θ is 150 °.
Compared with prior art, the superior effect of sight glass is at the bottom of the optical fiber door described in the utility model: sight glass has been realized 360 ° of omnibearing observations by right-angle prism is installed at the bottom of the optical fiber door described in the utility model before described object lens, realized the integrated transmission of sound signal and vision signal by installation audio collecting device and video collector, and adopted the monitoring in real time in dark surrounds of infrared illuminator and digital high-definition twilight image sensor, gathered clear picture.
