全息照片木纹噪声的产生与抑制

Generation of the wooden fringe noise of hologram and prevention

本文指出全息照片的木纹噪声，是由于记录干版的两端面不平整度而引起的。它的存在严重地干扰了显示全息的图像（无论彩虹全息和体积反射全息），故必需给予抑制。文中还详细讨论了拍摄不同全息照片时，所采用的不同抑制木纹噪声方法。

It is demonstrated that generation of the wooden fringe noise ofhologram is attributed to two plane non-parallel of the recording plate in the paper.The existence of wooden fringe noise of hologram seriously affects the image ofholographic display ( both rainbow hologram and volume reflection hologram ),so thewooden fringe noise of hologram must be prevented.This paper also gives a detail discussion that the different methods to prevent thewooden fringe noise are used to different hologram.
