【Abstract】 By\} extending information theory to sampled imaging system, the performance of image gathering device is assessed according to mutual information . Information theory\|based computer simulation results are given. Information theory\|based design parameters which are used to optimize system are proposed. According to simulation results, the general matching features and ideal matching condition between optical imaging system and CCD detector array are obtained. Experimental results on image gathering verify the result of theoretical analysis and simulations.更多还原
