A new mutiplex speckle photography is given which uses a rotating prism to record multiple specklegram. The advantage of this method is that the multiple specklegram of some dynamic process of an object can be recorded on a single holofilm. In the whole field filtration, the information of deformation in all channels can be easily obtained and the images obained are quite clear. Test results and analysis of the recorded dynamic deformation of a moving object and plate bended deformation are presented. It is shown that the theoretical analysis agree with results from test.
