摘　　要：叙述一种散斑照相法测量面内位移的数字显示方法 .采用实时测量 ,用 CCD记录散斑图样 ,离散化的数据送入计算机 .计算机的数字显示可产生较好的条纹图样和位移测量值 .给出悬臂梁微小位移的实验结果 .Numerical display of inplane displacement measurement by electronic speckle photography is described. This technique is a realtime measurement. The speckle pattern is recorded by a CCD camera, and the discrete data are sent to the computer. The numerical display of the computer can yield better fringe pattern and displacement measurement value. Experimental results of small displacement for cantilever beam are given. The results have verified the correctness of this technique.
