Embodiment Construction

[0041] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] Such as figure 1 As shown, this embodiment clarifies the basic working principle of laser anti-sniper detection. Laser anti-sniper detection emits lasers to the detected area, usually invisible near-infrared lasers (such as 808nm, 910nm, etc.). "Cat's eye effect", after the incident laser converges on the imaging focal plane, it will return in a route approximately parallel to the incident light, and thus be detected by the CCD on the laser anti-sniper detector.

[0043] Due to the "cat's eye effect" and for safety reasons, anti-sniper detection observers usually do not need and should not...

Abstract

The invention discloses an anti-laser anti-sniper detection method, which is characterized in that a glass window coated with a near-infrared cut-off film is installed on the optical front end of equipment requiring anti-laser anti-detection, and the plane of the glass window and the external laser anti-sniper detection method are adjusted. The laser beam emitted by the sniper detector forms a certain angle, so that the reflected light of the laser beam falls outside the detectable area of ​​the laser anti-sniper detector. The invention can effectively prevent the "cat's eye effect", and at the same time solve the problem that the sniper scope and reconnaissance equipment are easy to be detected by laser active anti-sniper.

Description

technical field [0001] The present application relates to technical fields such as reconnaissance and anti-reconnaissance, and in particular to an anti-laser anti-sniper detection method and device. Background technique [0002] In the field of reconnaissance technology, especially in sniper reconnaissance, the existence of anti-sniper detection devices poses a great threat to snipers and scouts. Usually, anti-sniper reconnaissance mainly includes sound and light detection, infrared heat detection and active laser detection; The anti-sniper means is laser active detection. [0003] Laser active anti-sniper detection uses the "cat's eye effect". By emitting a laser beam in an invisible band and using the principle of a sniper sight or observer to reflect light, the reflected light is received to detect the position of a sniper or scout. [0004] At present, conventional sniper scopes and reconnaissance equipment have no effective countermeasures against laser active anti-sn...
