应用三干涉图法测物体变形全信息

All Informations Measurement of an Object Deformation with 3—Interferograms—Method

本文从原理和实验两方面,论述了如何实现三个干涉图法的自动计算全息图,把这种方法应用到实时全息术上,获得物体表面变形的全信息:大小、方向和形状。做为实例,我们测量了二元胶体的收缩。这里仅例举一个过程,以证实该方法的实用性。

In this article we have theoretically and experimentallydiscussed,how automatic hologram calculation will be realized,and howwe apply this method to real--time holography,so we have all informa-tions:deformation quantity,direction and form of an object surface.As apractical example,we have measured the shrinking of 2--components adh-esive,here we illustrate one process of it to prove this method.
