| Abstract: | Several problems that should be considered for the design of the underwater imaging detection system are analyzed and discussed, including system parameters, optical signal computation model and imaging system performance evaluation model. Considering the distance between emitting system and receiving system, general theory model of underwater imaging detection system is built. The computing methods of signal radiance, back-forward radiance and forward radiance are deduced. The working distance equation of underwater imaging system is presented. |
