Range-gated System Design Based-on CPLD of Laser Active Imaging

摘要

Laser active imaging technology use near - infrared laser as illuminated source. And detect and imaging in weak brightness and long range. Range-gated technology is the key technology of active imaging system and this technology can overcome back scatter of the laser imaging system and enhance the SNR of the received images. Synchronization control technology is the crucial technology in range-gated laser active imaging system and it can guarantee the quality of the imaging. In this paper detailed expound on the principle of laser active imaging 、the design of synchronism control system and realize of range-gated.
