Computer Simulation for Underwater Photoelectric Imaging System

In view of the shortcomings of the Jaffe model,a theoretical model of underwater photoelectric imaging system is established for underwater target detection using the small angle approximation principle.Considering the influence of scatted light,the calculation method of signal radiation quantity and the contrast model of pixels in underwater imaging plane of a given distance is proposed.An underwater imaging detection system with extra light source is simulated.The relationship of the distances between the light source system and the acceptance system and the image contrast is researched.Compared with the Jaffe model,the physical meaning of the variables in the proposed model is clearer,and the simulation results are similar,which proves the correctness of the proposed method.
