Wherein, in order better to show the operating state of night vision device, also be provided with status indicator lamp 6 on the night vision device, show in real time the operating state of night vision device.
The operation principle of this night vision device of the following detailed description is as follows:
After mains switch 11 closures, external wire 12 is through the first power transfer module 1 of 11 pairs of IMAQs of mains switch and display part and second source modular converter 13 power supplies of near-infrared laser light source, the first power transfer module 1 begins to providing suitable voltage and current to imageing sensor 4, image processing module 5, liquid crystal display 2, second source modular converter 13 provides suitable voltage and current for near-infrared laser light source 3, at this moment status indicator lamp 6 Chang Liang; The plane at the face place of liquid crystal display 2 demonstration images and imageing sensor 4 receive the plane parallel at the face place of light, and the long limit of rectangular liquid crystal display 2 is parallel with the long limit of rectangular imageing sensor 4, and the direction of motion of the moving object that liquid crystal display 2 shows is consistent with the actual motion direction of moving object; The center line of near-infrared laser light source 3 light emitted bundles is vertical with the plane, face place that imageing sensor 4 receives light; Between imageing sensor 4 and camera lens 10, or suitable near-infrared narrow band pass filter 9 and the first near infrared polarization mating plate 8 are added in camera lens 10 fronts; Near-infrared narrow band pass filter 9 is parallel with the face that imageing sensor 4 receives light, the centre wavelength of near-infrared narrow band pass filter 9 is consistent with the centre wavelength of near-infrared laser light source 3 light emitted lines, the half-band width of near-infrared narrow band pass filter 9 is greater than the breadth of spectrum line of near-infrared laser light source 3 light emitted lines, perhaps the two approximately equal; The plane parallel at the face place of the reception light of the first near infrared polarization mating plate 8 and imageing sensor 4, the centre wavelength of the polarization scope of the first near infrared polarization mating plate 8 is consistent with the centre wavelength of near-infrared laser light source 3 light emitted lines, the breadth of spectrum line of the polarization scope of the first near infrared polarization mating plate 8 is greater than the breadth of spectrum line of the light emitted line of near-infrared laser light source 3, or the two approximately equal, the polarization direction of the first near infrared polarization mating plate 8 becomes 45 degree inclination angles with imageing sensor 4 long limits; There are two orthogonal polarization directions in the light that near-infrared laser light source 3 is launched, the light of one of them polarization direction is stronger, the light of another one polarization direction a little less than, when near-infrared laser light source 3 is installed, need to allow the stronger polarization direction of near-infrared laser light source 3 light consistent with the polarization direction of the first near infrared polarization mating plate 8; If the light intensity of 3 two orthogonal polarization directions of near-infrared laser light source differs large not, the second near infrared polarization mating plate 14 need to be installed in near-infrared laser light source 3 fronts, the parameter of the second near infrared polarization mating plate 14 is consistent with the parameter of the first near infrared polarization mating plate 8, the second near infrared polarization mating plate 14 is vertical with the center line of the light beam that near-infrared laser light source 3 sends, the polarization direction of the second near infrared polarization mating plate 14 is consistent with the polarization direction of the first near infrared polarization mating plate 8, and the light that sends of near-infrared laser light source 3 becomes complete polarized light after through the second near infrared polarization mating plate 14 like this.Because the light that near-infrared laser light source 3 sends is polarisation larger polarised light or complete polarized light frequently, so when the near-infrared laser light source 3 of two night vision devices faces shooting, the polarization direction of the light that near-infrared laser light source 3 sends is vertical with the polarization direction to the polarized light piece before the imageing sensor 4 of near infrared light sensitivity of another night vision device of opposite, therefore the light that sends of near-infrared laser light source 3 seldom or can not enter in the imageing sensor 4 of opposite night vision device, therefore two impacts that just can not be subject to the LASER Light Source of opposite night vision device in the face of the IMAQ of the night vision device taken.
