摘要
介绍一种用计算机模拟再现傅里叶计算全息图的方法 ,它不但比传统的光学再现更方便和快捷 ,还可以通过调节各种参数来模拟和研究影响再现质量的实验条件。给出了由于全息片表面不平、曝光过度或不足、分辨力高低等条件下再现像的模拟结果 ,证明该方法是研究计算全息图再现的有效方法。
A method for reconstructing computer-generated Fourier hologram with computer simulation is introduced. It is not only more convenient and quicker than the traditional optical reconstruction, but also can simulate and study experimentally the conditions affecting the reconstruction quality of images through adjusting various parameters. The simulation results for the reconstructed images under conditions such as uneven surface of holofilm, excessive exposure or insufficient exposure, high or low resolution, etc. are given. The above results demonstrate that this is an effective approach for studying the reconstruction of computer-generated hologram.
