Abstract
In a fringe analysis method comprising the step of subjecting fringe image data carrying wavefront information of an object to be observed to Fourier transform method so as to determine a wavefront of the object, the fringe image data is multiplied by a window function corresponding to an effective data area of the fringe image data before the Fourier transform method is applied to.
