一种利用象散改进的白光重现全息术
White-light reconstruction holography improved with astigmatism
摘要
在普通的象平面全息术中,重现象跨立在全息图上,在全息图前方的象将引起视觉的混乱.本文用离轴象散理论得出能使象平面全息术的白光重现象位于全息图后方,从而避免视觉混乱的实验条件,并给出相应的实验结果.我们用这种方法,获得了清晰、明亮、没有斑纹,并且位于全息图后方的白光重现立体象.
Abstract
Drdinary image-plane holography requires the reconstructed image to straddle over the hologram, thus the image in front of the hologram causes visual confusion.This paper describes our experiments using non-paraxial astigmatism theory to make the white-light reconstructed image on the image-plane holography appear behind the hologram, thus avoiding visual confusion. All conditions for the experiments and the results are given in detail. Using this method, we have obtained a clear, bright, speckle-less white-light reconstructed stereoscopic image, located behind the hologram.
