Laser warning device

Abstract

The invention discloses a laser warning device, which comprises an optical receiving system, a photoelectric sensor, a signal processor, a display and warning device and a photoelectric interference device. A glass ball with a graded refractive index internally adopts a cavity structure; the glass ball with a graded refractive index is internally provided with the photoelectric sensor; and the signal processor is connected with the photoelectric interference device and the display and warning device. Quick detection can be realized; the horizontal viewing angle is 360 DEG; the pitch angle theta has a range of -pi / 2< / =theta< / =pi / 2; the orientation accuracy is high; threatening laser can be detected in a short time; the false alarm rate is low; the angular resolution ability is high; and the viewing angle is large.

Description

technical field [0001] The invention relates to an alarm, in particular to a laser alarm. Background technique [0002] Due to the excellent performance of laser, it is used in different fields, especially in the application of war, which makes the battlefield full of laser threats, in order to avoid being hit by laser weapons. Laser warning devices came into being. The warning device can detect the laser, notify the threat before being hit by the laser weapon, and make one's own side survive through interference or evasion. of great importance. Laser has characteristics such as coherence, monochromaticity, and directionality that other light sources cannot match, which makes it the darling of high-tech warfare. Laser target designators, laser radars, laser rangefinders, etc. have become the trump cards in the war. It is precisely because of the existence of these trump cards that they threaten their own safety and promote the development of laser technology. The laser w...

Problems solved by technology

The above three laser warning devices can only receive directly incoming laser light, but cannot provide laser warning by detecting the laser energy scattered by the atmosphere. In the prior art, the laser warning optical system of the traditional laser warning device has a slow detection speed for laser light. The angle of view is not large enough, the false alarm rate is high, the orientation accuracy is not high, and there are many defects. With the development of the military, the traditional laser warning device can no longer meet the needs
