Research on night vision distance imaging technology of semiconductor laser

Abstract

The semiconductor laser night vision distance imaging system introduced in this paper is an active imaging system with a laser as a light source, forming an image according to the light reflection difference of the target and the background. Compared with the passive imaging system, the active imaging system has the characteristics of strong receiving signal. Under extreme conditions, it can also realize the extraction of image key information of strong reception signal. Under extreme conditions, it can also realize the extraction of image key information through range-gated technology. It is a high anti-interference capability semiconductor laser ranging imaging technology suitable for severe weather and conditions. The system can be used in laser active imaging guidance, unmanned aircraft, guidance systems and other military fields and public security, fire control, transportation and other fields.
