Abstract
Repositing a single exposure hologram to its original place precisely and real-time measuring the phase distribution of the deformed object wave are the foundation of real-time holographic interferometry. In general, phase distribution of the under testing object wave must be determined by measuring the corresponding intensity distribution of several phase shift interferograms. An digital method is introduced in this paper, it greatly simplify the process of determination for the phase distribution of the under testing object wave by using only one interferogram and reduce the precise requirement of the real-time hologram reposition. Some experimental examples are also given in the paper.
