二次曝光全息干涉计量技术研究应力场

该文回顾了全息技术的发展历史，阐述全息技术的现行状况和相关的发展。从两个方面论述二次曝光全息技术研究应力场实验所需要的理论基础，第一个方面是论述全息照相技术的理论基础，第二个方面是论述了全息干涉计量学的相关理论，重点阐述二次曝光全息计量和漫射体全息干涉计量的基本理论。该论文用二次曝光全息干涉技术研究漫射体受力所产生的应力场，即将物体受力前后的两次全息信息记录在全息干板上，干板上形成漫射体的干涉条纹图，通过分析干涉条纹可以知道漫射体应力场的分布情况。

The Study of Stress Field by Double - Exposure Holographic Interomentry

This article reviews the development history of the holographic interferomentry and discusses the recent status and the related development.It discusses the required theory to study the stress field of the diffuser with double-exposure holographic interferomentry from tow ways.On the one hand,discussing the basic theory of holographic photography.On the other hand,discussing the related theory of holographic interferomentry.In this paper we mainly discuss the basic theory of the double-exposure holographic interferomentry and the diffuser's holographic interferomentry.This paper studies the stress field of the diffuser when it occurs deformation by the outside strength.By recording the information of the diffuser at the holographic plate when it is pressed by the outside strength and itn't.And then on the plate will appears the fringe of the diffuser.By analyzing the fringe,we can know the distribution of the stress field of the diffuser.
