Abstract: With the help of a new multichannel speckle shearing photography,a study is conducted of influence on a copper thin slice strain after SMA is embedded. In this photography the rotating optical link converter is put in the light path to change the imaging positions so that the multichannel recording is realized.In one recording medium three speckle patterns of amamorphic state are recorded,and at the same time,with the help of full field filtering analysis,the amamorphic information of these channels be presented conveniently and compared easily.The paper gives theory analysis and experiment results. Which show that after embedding SMA,the matal material has stronger rigidity.
