本文就1200mm×800mm激光实验台测得的数据和结果,分析了在Fourier变换激光全息图象和文字存储的光路中二光束分束比、二光束夹角和离焦量等因素对存储效果的影响,说明了获得较好地Fourier变换激光全息图象和文字的存储效果的必要条件。
In this paper, 1200mm × 800mm laser test bench measured data and the results analyzed in the Fourier transform laser holographic image and text stored in the optical path of the two beam splitting ratio, two beam angles and defocus amount and other factors on the storage effect Influence, illustrates the necessary conditions for obtaining a good Fourier transform of laser holographic images and text storage effects.
