Paper Abstract

Noisy interferometric signals and distorted interference fringe patterns analysis is very important for solving problems of metrology and nondestructive testing. In this paper the possibilities of the new nonlinear locally-adaptive filtering method were explored. This method can be used for preliminary noise suppression of fringe patterns at phase retrieval and for extreme lines location. It was verified experimentally high noise-immunity of the method proposed when processing real-obtained noisy distorted fringe patterns.
