摘要
用Ar+激光器作光源,用硅酸铋晶体作全息记录介质,把三个干涉图法应用到双曝光全息干涉术,从而实现了全息干涉图的自动计算,获得被测物体表面变形的大小、方向和形状的全部信息。为验证该方法。
Automatic computing for hologram is realized by using Ar + laser as a light source and BSO crystal as a holographic recording material,and using tri-inter- ferogram technique on double- exposure holographic interferometry.As a result all the information of the dimension,form and direction for surface deformation of the measured object can be acquired.In order to verify this technique,the deformation measurement of a thin plate under stress is carried out.
