%X Based on the Fresnel diffraction theory, the point spread function of digital holographic system with pre-magnification was firstly deduced in detail. The resolution of the imaging system was analyzed. The amplitude distributions of the point spread functions of the microscopic objective, the CCD and the whole system were simulated respectively. Then, the match requirement between the microscopic objective, and the CCD was discussed. Some ambiguties in existing literatures were clarified.The results show that making the imaging resolution of MO approached the limit resolution and the imaging resolution of CCD been equal to or higher than the resolution of MO slightly by chosing the recording parameters pertinently are optimizational choices. These results will be very important in the microscopic digital holography.
