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.
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。
