A Study for Making a Thin Silver Halide Phase Hologram with an Expectation Phase Modulation

提出基于空间－角度复用技术的盘式三维全息存储方案，给出这一技术的基本原理，并采用简化的光线分析方法对该方案的可行性进行分析。研究表明，这是一种能提供高密度和高数据传输率、而读写系统又相对简单的盘式三维全息存储方案，具有潜在的应用前景。

A new method for making a thin silver halide phase holographic grating with an expectation phase modulation is proposed. The optimum exposure parameter can be obtained by analysing the data of the holographic grating which was made at the first step. Then the subsequent thin phase holographic gratings with expectation phase modulation can be made under the same experimental conditions as in the first step. The theoretical analysis and some applications of this method are discussed.
