摘　　要：本文指出全息记录材料可看作一散射物体，当激光束通过它后形成散射光，对全息再现象来说，它就是散射噪声，利用细激光束很容易测量出散射噪声和记录材料中散射颗粒的大小，后者对干板的鉴别率起着决定性的作用，而鉴别率不够，将会导至全息记录的彻底失败。并报导了；如何利用细激光束的散射图象，来分析模压全息图片和全息再现像的波像差，以及在全息干涉计量中用细激光束成像从干涉条纹获取信息的方法。In this paper,the holographic recording materials are thought as the scatting object,while a narrow laser beam irradiates to the recording materials,the scattering light must be emerged.For the reconstructing hologram,the scattering light is thought as the noise.By use of the narrow laser beam,the scattering noise and the particle size of the recording materials can be measured.As the particle size of the recording materials determined the resolution power of the holographic plate,so the resolution power determined the quality of the hologram.This paper also gives out the wave aberration for embossing hologram and holographic reconstructiong image by using the scattering image of the narrow laser beam,and the method to obtain information from interference fringe.
