The information theory is applied to the sampling imaging system, the performance of the image capture part is evaluated by mutual information, and the simulation curve of the system evaluation is made based on information theory. The index of system optimization design based on information theory is proposed. According to the simulation results, the macroscopic matching characteristics and the best matching conditions between optical imaging system and CCD array detector are given. The experimental results of image capture prove the correctness of theoretical analysis and simulation results.
