一种显示位相体三维位相分布的彩虹全息法

A Rainbow Holographic Method for Displaying the 3-D Phase Distribution of a Phase Object

本文提出一种利用简单一步彩虹全息术显示位相体三维位相分布的新方法．文中对两次曝光记录和显示位相体的原理进行了理论分析，计算了彩虹全息图狭缝实象的位置．并讨论多次曝光获得假彩色编码象的可能性．理论分析和实验结果是一致的．

The paper presents a new method for displaying the 3-D phase distribution of a phase object using the simple one -step rainbow holgraphy. It theroetically analyses the principle of recording and displaying the phase object with two -exposures , and calculates the position of the real slit image reconstructed from the rainbow hologram.The possibility to obtain the pseLldo - colotlr image with multi - exposulres is also discussed. The theory agrees with the experiment.
