Laser irradiator with infrared composite imaging system

Abstract

A laser irradiator with an infrared composite imaging system comprises a laser emission system, an infrared receiving system, an image mixing system and a display. The laser emission system is used for emitting a laser beam so as to irradiate a target. The infrared receiving system is used to receive a laser echo signal acquired when the target carries out diffuse reflection. The image mixing system is used to mix two paths of infrared imaging information through an FPGA image processing circuit and transmit to the display. The display is used for receiving a mixing signal output by the imagemixing system. Through integrating a laser spot and a long-wave infrared imaging mixing display system in the laser irradiator, the portability of equipment is increased. Target infrared image information and the position of the laser spot can be observed in real time through the display so that the application range of the equipment is greatly improved, the precision of laser-guided ammunition strikes is increased, and tactical time is shortened.

Description

technical field [0001] The invention relates to a laser irradiator with an infrared composite imaging system. Background technique [0002] Since the advent of the laser, the needs of the military field have always guided the development of laser technology. The laser irradiator is a kind of increasingly mature military laser equipment, which emits laser light to the target, and the guided munition finds the target according to the diffuse reflection beam of the target, and strikes it. [0003] Laser irradiators play a huge role in modern warfare. Compared with traditional TV guidance and other means, laser guidance has higher accuracy and reliability. After decades of development, from the initial lamp-pumped laser to the current semiconductor laser, the volume and weight of the laser irradiator have been greatly reduced, greatly improving the portability of the battlefield. Although the technology is developing rapidly, there are still many defects in the laser irradiato...

AI Technical Summary

Problems solved by technology

[0004] (1) The individual laser irradiator needs to cooperate with the laser spot meter to determine the actual irradiation point, and the actual irradiation point cannot be determined only through the optical eyepiece crosshair of the laser irradiator

[0005] (2) The individual laser irradiator cannot accurately confirm the target position through the optical eyepiece in the environment of smoke, dust, night, etc., and needs to be observed with an infrared thermal imager

[0006] The above two defects greatly limit the conditions of use of individual laser irradiators
