基于TMS320DM642的光栅型激光告警系统的设计与实现

摘要

为迅速无误地获得来袭激光的波长和方位角信息,根据光栅衍射原理,设计了基于TMS320DM642的光栅型激光告警系统.该系统采用优化的图像处理算法,能够迅速判别来袭激光.实验表明:该系统有效探测来袭激光波长范围为800～1500 nm,精度为10 nm,角度分辨率为2°.%To quickly obtain correct incoming laser wavelength and azimuth information,we design a grating type laser warning system based on TMS320DM642 according to the principle of diffraction grating.This system uses optimized image processing algorithms to achieve rapid identification for incoming laser.It is shown than the system can effectively detect incoming laser wavelength range:800 ～1 500 nm,the accuracy of 10nm,the angular resolution of 2 degrees.
