S. Denicola et P. Ferraro, A 2-DIMENSIONAL FAST FOURIER-TRANSFORM METHOD FOR MEASURING THE INCLINATION ANGLE OF PARALLEL FRINGE PATTERNS, Optics and Laser Technology, 30(3-4), 1998, pp. 167-173
In this paper we describe a technique based on two-dimensional fast Fo
urier fringe pattern analysis for the automated evaluation of the incl
ination angle of parallel fringe patterns. Analysis of noise-free theo
retical parallel fringe patterns is presented and numerical results of
the angle evaluation error using this algorithm are discussed. We als
o demonstrate an application of the method to the measurement of the i
nclination angle of experimental parallel fringe patterns. (C) 1998 El
