摘要
文章披露了全息光栅，散射物体的离轴全息和彩虹全息图片，在５０００倍扫描电子显微镜下的照片。并从理论上解释了它们的显微结构。指出它们是散射物体在干版上的菲涅尔交换频谱与参考光相干涉的结果。指出这种显微结构是散射物体全息照片衍射效率低於全息光栅的根本原因，并提出了改进拍摄办法，以增加衍射效率。
In this paper,we reported five-thousand scanning electronmicroscope photograph of off-axis and rainbow holographic plates about scatted object and holographic grating.Some theoretical explain about microstructure have been given.It was proved that Fresnel transform frequency spectrum interact with reference beam to result in microstructure.It was the microstructure that cause the diffraction efficiency of scattered object to low.We also pointed out some methods how to take and add the diffraction efficiency.
