摘要
本文对制作高质量、大版面体积反射全息图提出了一些改进意见，包括用光学双稳装置抑制由于外界扰动造成的干涉条纹的随机漂移，用１／２波片消除木纹噪声，为了提高衍射效率和信噪比，在拍摄参数上进行了选择，并在实验中取得了很好的效果。
This paper presents some new methods in taking big plate reflecting hologram, including to use the bistable optical device to locking interference fringe, 1/2 wave plate to prevent wooden fringe noise and to choose taking suitable parameters to improve signal to noise ratio with suitable diffraction efficiency. By use of these methods, the quality of the reflecting hologram is improved in our experiment.
