Abstract

In this paper, the principle as well as the implementation of EPISM method are introduced firstly. In order to evaluate the reconstruction quality better, the imaging process of EPISM based holographic stereogram is regarded as a general optical system imaging, and modeling and optimization of EPISM method are proposed from two different aspects of angular spectrum and spatial domain. In the analysis of angle spectrum theory, the exit pupil function model is simplified firstly and the optical transfer function (OTF) with defocusing aberrations was established. In spatial domain analysis, the modulation characteristics of the hogel based holographic stereogram is constructed and validated while a diffraction-limited imaging model of the hogel based holographic stereogram is established, and the effective resolvable size of the reconstructed image point is simulated. The theories show that there is an optimal hogel size existed for the certain depth of scene. Optical experiments demonstrate the validity of our analysis, and the optimized parameters of hogel sizes can improve the imaging quality of full parallax holographic stereogram effectively.
