【摘要】 本文提出了动态散斑照相的一种新方法─－旋转光楔散斑照相术．文中给出了理论分析及实验结果。该方法不仅能在一张记录介质上记录物体动变形的各状态的多通道散斑图，而且用全场滤波分析时，能方便地同时给出所有通道上的物体变形信息，得到清晰的、高衬比的干涉条纹图。这种方法是利用旋转光楔照相机来实现多通道动态散斑记录，具有设备简单、用途广泛等优点。文中给出了实测结果，理论分析与实验结果是吻合的。更多还原

【Abstract】 in this paper,a new method of dynamic speckle photograph--rotating optical wedge speckle photogrophy is proposed. The theoretical analysis and preliminary experimental results are presented. The advantage of this method is that multiple specklegram of some dynamic process of an object can be recorded on a single holofilm. In the whole field filtering,the information of deformation in all multiples can be easily obtained,and images obtained are quite clear. This method uses a rotating optical wedge speckle camera to record multiple specklegram. Test results are presented and the results coincide exactly with theoretical analysis.更多还原
