Abstract

Analysis of noisy interferometric signals and distorted interference fringe patterns with complicated structure is very important for solving problems of metrology and nondestructive testing. New nonlinear fringe processing method with spatially dependent filter impulse response is investigated. Unlike conventional filtering methods, in this method a filter impulse response is formed by the local empirical histogram modification with the spatial weighting function inside a dimensionally varied area dependent on the local fringe intensity distribution. High noise-immunity of the method proposed was verified experimentally when processing real noisy distorted fringe patterns.
