R. Castaneda et J. Garcia-sucerquia, Fourier analysis applied to the characterization of optical wedges with small angles, APPL OPTICS, 38(31), 1999, pp. 6522-6527
A technique for the measurement of optical wedge parameters is shown. It is
based on the analysis of the Fourier transform of an interferogram-intensi
ty register. In this domain the angle and the edge orientations of the opti
cal wedge can be determined through a much simpler procedure than the usual
interferogram fringe analysis. (C) 1999 Optical Society of America. OCIS c
