【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.更多还原

【Abstract】 The ordinary image-plane holography reguires the reconstructed image to straddle over the hologram, thus in consequence the image in front of the hologram causes visual confusion. This paper describes the experiments, we have made, by using non-paraxial astigmatism theory, to make the whole white-light reconstructed image of image-plane holography appear behind the hologram, thus avoiding visual confusion. All the conditions for the experiments and the results are given in detail. Using this method, we obtain a clear, bright, speckle-less white-light reconstructed ster-reoscopic image, which is located behind the hologram.更多还原
