Abstract
A grating diffraction laser warning system is a type of electro-optic countermeasure equipment based on grating diffraction,it can detect the parameter information of the incident laser in real-time.To get the wavelength and the azimuth of the incident laser,with the grating diffraction principle,the image signal was acquired by a area planar array CCD,the image processing was done by digital signal processor,and the image processing algorithms were exploited.The theory was analyzed and experimental results were verified,the image acquisition and processing of the grating diffraction laser warning system based on area planar array CCD was designed,the detection of the incident laser was realized.The experimental results show that the system can detect and mark the incident laser effectively,the system is stable and real-time.
