white light speckle

基本解释

Strain concentration factors of circular cylinders with circular and square holes wereanalyzed by a white light speckle method.
用白光散斑方法进行了带圆孔和方孔圆筒应变集中系数分析。
The rotating aperture method is used in de focused white light speckle photography, and the experimental result is in agreement with the theoretical analysis.
把转孔法用于离焦白光散斑照相，实验结果同理论分析保持一致。
One characteristic of white light speckle method is the fact that the artificial speckles are attached to the specimen so that they follow the displacement or deformation of the specimen precisely.
在白光散斑法测量中，物体表面上的白光散斑场跟随着物体一起运动，所以三维物体表面的变形向量就是白光散斑运动的位移向量。
