    Abstract

    In this paper, a new method of dynamic speckle photography——rotating speckle-shearing interferometry is proposed. The theoretical analysis and preliminary experimental results are presented. The advantage of this method is that a whole dynamic process of an object can be recorded on a single specklegram. In the whole-field filtering, the information of deformation at any instant can be easily obtained, and images obtained are quite clear.
