| Abstract: | This paper introduces an experiment of recording pictures by CCD pickup camera instead of conventional holographic dry plate,which are stored in computers to be treated, realizing the observation of relative fringes of interference scattered-spot field on TV screen.so as to measure tiny movement of object. It is a comprehensive experiment with the combination of light,electricity and computer. |
