Risk analyzing of high energy laser effecting on photodetector

It is usually needed to analyze the risk of high energy laser effecting on photodetector in electro-optical EW system test and the design of photoelectric measure system. Firstly, the transmission formula of 1.06 μm and 10.6 μm laser in atmosphere is introduced, and the optical gain of photoelectric system is analyzed. Then the energy density of photodetector received on the base of actual CCD and infrared camera parameters is calculated. At last, by comparing with damage threshold of photodetector, the damage risk of photodetector can be received. It can be referenced in electro-optical EW system test and the design of photoelectric measure system.
