摘 要: 本文提出一种改进的简单一步彩虹全息法,根据光的衍射理论,分析采用狭缝光源照明物体记录彩虹全息图的可能性,并讨论了彩虹像的单色性、色模糊、线模糊、分辨率及视角.最后给出实验结果.这种方法具有分辨率高,光能利用率高和操作简单等特点. An improved simple method of one-step rainbow hologram is presented in this paper.Accordingto the theory of light diffraction,analysis is made in the possibility of making rainbow hologramusing a slit-like source.Also discussed are image monochromaticity,colour and line blur,resolutionand viewing angle.Experinental results are given.The method has the characteristics of goodresolution,full utilization of light energy and simplicity of operation.
