This paper discussed a method analyzing the two-step rainbow hologram. Based on the diffraction theorem of light wave, the imaging formulas of object image and slitimage were derived in detail.
本文讨论了一种分析二步法彩虹全息的方法，用光波衍射理论详细推导出物体象与狭缝象的成象公式。

It consists of a magnetic scanning system, a thick slit, a fluorescent screen and a CCD image processing system.
它包括有磁扫描系统，厚窄缝，荧光屏以及CCD图像处理系统。

Bying adding an oscillator mirror in the imaging path, thus the enlarged image will be scanned by the narrower slit, and the optical boundary information is converted into gradient electrical pulse.
