Abstract
By analyzing the spatial fringe analysis method wiht the communication theory, it has been shown that the meauring accuracy of the method depends onthe cahracteirstics of ameasured object. It is also shown that not only the inherent limitation of the accuracy but also the dependence upon the S/N ratio of the fringe images exist inteh spatial fringe analysis method. It is shown that filtering technologies are useful to improve the measuring accuracy in fringe analysis.
