提出了一种新的多通道散斑照相术，通过旋转光楔实现多通道散斑图记录。该方法不仅能在一张记录介质上记录物体动变形一些状态的多通道散班图，且用全场滤波分析时，能方便地同时给出所有通道的物变形信息，得到清晰的，高衬比的干涉条纹图。文中还给出了物体动变形及板弯曲等实测结果及分析。结果表明，理论分析与实验结果相一致。
A new multi-channel speckle photography is proposed, which can record multi-channel speckle images by rotating optical wedges. The method can not only record the multi-channel scatter class diagram of some states of a moving object on a recording medium, but also can easily give the deformation information of all the channels at the same time by using full-field filtering analysis to obtain clear and high-lined Interference fringe pattern. The article also gives the measured object moving deformation and bending test results and analysis. The results show that the theoretical analysis and experimental results are consistent.
