一、引言用光学全息法测量物体变形矢量包括两个内容,第一,测量物体变形量;第二,测量物体变形方向。对第一个问题国内外研究较多,对第二个问题现在国内有人研究。但他们分别只研究了其中的一个问题,并没有综合考虑两个内容,这是不足之处。本文在分别给出了测量物体变形量和判别物体变形方 I. INTRODUCTION To measure the deformation vector of an object by optical holography includes two contents. First, measure the deformation of the object. Second, measure the deformation direction of the object. There are more studies on the first question at home and abroad, and some people in the country now study the second question. However, they have studied only one of them and have not considered both of them together. This is a deficiency. In this paper, we give the measurement of object deformation and object deformation
