【摘要】 本文提出一种用二步法制作彩虹全息图的方法。它不同于Benton的二步法,其特点是:(1)采用了矩孔光栏;(2)象面接收。这样制成的全息图具有大的视角;可用白光近距离照明再现,兼有三维、彩虹、象面全息特点。文中介绍了光路设计、参数选择及实验结果。更多还原

【Abstract】 This paper has advanced a new kind of method for making wide-angle rainbow-hologram. It differs from Benton’s two-step method in two aspect: (1) the replacement of the single slite by the rectanglar aperture, (2) the adoption of image-plane reception. Hence our making hologram is a wide-angle hologram, which has characteristics of a rainbow-hologram, an imaged-hologram and a three dimension hologram. Its images can be reappear by illuminating the hologram with an incandescent lamp at a short distance. This paper will introduce to the reader our optical design, relevant parameters and results of experiments.更多还原
