Study on information content of the 3D object's coherent imaging and hologram information redundancy

On the basis of the light field distribution of objects with coherent illumination, and the most basic physical mechanism of binocular stereoscopic vision, we calculate the information content of the light field in ‘the smallest observation window’ produced by a point source and multi-points source...

Description
Summary:On the basis of the light field distribution of objects with coherent illumination, and the most basic physical mechanism of binocular stereoscopic vision, we calculate the information content of the light field in ‘the smallest observation window’ produced by a point source and multi-points source respectively, and ‘the smallest observation window’ means that the size of the window just satisfies the demand of binocular stereo vision. As a result, the minimum information content of the light field that the binocular stereo vision needed is acquired. Comparing the information content of hologram with that of the light field in the hologram plane, we make out the redundancy of holographic information content and point out the direction of the holographic compression.
