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。
This paper points out that the holographic recording material can be regarded as a scattering object. When the laser beam passes through it, it forms scattered light. For holographic reconstructions, it is scattering noise. Scattering noise and scattering particles in the recording material can be easily measured by a fine laser beam The latter of the dry plate identification rate plays a decisive role, while the identification rate is not enough, will lead to a complete failure of holographic records. And how to use the scattered laser beam to analyze the wave aberrations of molded hologram and holographic reconstructed image and obtain the information from the interference fringes by using the fine laser beam imaging in holographic interferometry.
