Abstract: By utilizing the theories of Fresnel diffraction and amplitude holography,the effects of configuration parameters on the numerical reconstruction of off-axis digital holographic recording system are analyzed and the corresponding experiment is operated.The results of theoretical analysis and experiment show: if the sizes of recorded object and CCD are fixed,the distance between the recorded object and CCD has a direct impact on the resolution of the system and the separation of the three images in reconstruction plane.If the premise of separation status of the reconstructed images is satisfied,shortening the distance between the object and CCD redounds to improving the resolution of reconstructed image.
