The integrated laser night vision device realizes the ultra-remote video monitoring in the security field, enables a camera and a laser device to utilize the same lens and realizes the purpose of remote monitoring by adopting a novel reflex lens, an optical structure and an electronic circuit, wherein the optical structure and the electronic circuit are matched with the novel reflex lens.
Description
One, technical field:
The present invention relates to a kind of night-vision devices, specifically a kind of integrated laser night vision device with single lens.
Two, background technology:
Existing laser illumination night vision supervisory system is to adopt video camera to add the twin-lens device that laser illuminator combines in the market.It is the supervisory system of the laser lighting that realizes by the focus controlling to video camera with to the control of laser illuminator crevice projection angle.But this supervisory system needs the use main control system that operating personnel can be very skilled, need operator respectively video camera and laser illuminator system to be controlled, just can reach best display effect, and the laser illuminator system remolding sensitivity of this supervisory system is poor, the laser projection angle of optimal imaging effect is difficult to regulate, and has caused the reduction of whole system operability.Also the night vision monitoring system that has some can realize synchronous zoom on market, be a kind of can be along with the crevice projection angle of the variation adjusted in concert laser illuminator of lens focus, make the visual field of camera lens change a kind of system matching with the crevice projection angle of laser.Although this system has solved the problem of video camera and laser illuminator adjusted stepwise to a certain extent, this supervisory system remains and is combined by video camera and laser illuminator system; Still the deviation that exists camera lens and laser lighting crevice projection angle to coordinate, last picture rich in detail is appointed so needs operating personnel's fine setting to realize, and video camera and laser instrument all need to adopt camera lens separately, not only manufacturing process complexity, volume is larger, and making use cost is also larger.
Three, summary of the invention:
The present invention is in order to realize the overlength distance video monitoring on safety-security area; Mainly realize the laser night-vision device that video camera and laser instrument adopt same camera lens; By adopting novel Zigzag type camera lens and supporting optical texture, the object that electronic circuit reaches remote monitor with it.
The present invention is achieved by the following technical solutions: it comprises collimating mirror, beam expanding lens, prism, the prism of turning back, optical glass window, birefringence camera lens and video camera imaging device, on structure of fiber_optic, be fixed with laser fiber, structure of fiber_optic connects collimating mirror, beam expanding lens, prism and the prism of turning back successively, rear focus lamp connects prefocusing mirror, prefocusing mirror connects once turn back prism and optical glass window, prefocusing mirror connecting secondary refractive lens, birefringence camera lens connects optical filter and video camera imaging device.
The present invention is the overlength distance video monitoring of having realized on safety-security area, realize the laser night-vision device that video camera and laser instrument adopt same camera lens, by adopting novel Zigzag type camera lens and supporting optical texture, the object that electronic circuit reaches remote monitor with it.Catadioptric camera lens utilizes the catadioptric principle of light, while making light pass through the first arrangement of mirrors sheet, is not directly to arrive sensor, but after two secondary reflections, just arrives sensor.The singularity of catadioptric lens optical structure makes its volume obtain and dwindle to greatest extent, and weight and cost have also decreased.And there will not be and affect the aberration of image quality phenomenon, image quality performance is good.Be specially adapted to the target observation of overlength distance.
Four, brief description of the drawings:
Accompanying drawing is structural representation of the present invention.
Five, embodiment:
With reference to accompanying drawing, the present invention includes collimating mirror 3, beam expanding lens 4, prism 5, the prism 6 of turning back, optical glass window 10, birefringence camera lens 11 and video camera imaging device 13, on structure of fiber_optic 2, be fixed with laser fiber 1, structure of fiber_optic 2 connects collimating mirror 3, beam expanding lens 4, prism 5 and the prism 6 of turning back successively, rear focus lamp 7 connects prefocusing mirror 8, prefocusing mirror 8 connects once turn back prism 9 and optical glass window 10, prefocusing mirror 8 connecting secondary refractive lens 11, birefringence camera lens 11 connects optical filter 12 and video camera imaging device 13.
In specific operation process, first the laser beam that large-power semiconductor laser instrument produces sends by the laser fiber 1 being fixed on structure of fiber_optic 2, the laser beam sending pools directional light via collimating mirror 3, and then change its dispersion angle by beam expanding lens 4, after light beam, enter prism 5 and the prism 6 of turning back, enter afterwards rear focus lamp 7 and prefocusing mirror 8, by prefocusing mirror 8 and rear focus lamp 7, light beam is carried out the operation of zoom and focusing, enter afterwards that the prism 9 of once turning back is rear finally to be launched by optical glass window 10, realize the function of long distance laser illumination, laser beam and the installation of the prism 9 of once turning back need to reach the requirement of parallel and contour arrangement, could realize like this imaging effect, when imaging beam returns from target to be monitored, first enter prefocusing mirror 8 and rear focus lamp 7 by birefringence camera lens 11, by prism 5 and the prism 6 of turning back, light beam is carried out entering optical filter 12 after 90 ° of reflections, the impurity that optical filter produces some laser beams filters, finally enter the rear generation image of video camera imaging device 13.
In the time of the monitoring that realizes distant object, when camera lens group is carried out the action of zoom zoom, the laser beam that laser fiber sends also synchronous zoom, to adapt to the change of distance of target to be monitored, has been realized the laser night-vision device of the single-lens synchronous zoom of Zigzag type.
