Abstract
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.
