Study on theoretical limit of information content of display hologram

Based on the definitions of information and information content, the information content of a spatial object point has been expressed. Furthermore, according to the most fundamental physical mechanism to produce binocular stereovision and light field distribution formed by coherent illuminating objects, space information content matched with human vision system is calculated and the minimum light field information content needed for binocular stereovision is obtained in this paper. And then, analysis on information content for holographic 3D display is made and theoretical limit of information content of display hologram is given based on these. It provides basis of minimum information content for hologram recording, transmission and display.
