Two-dimensional sinusoid fitting and Fourier transform methods of analyzing fringes to determine the wave-front topography are described. The methods are easy to apply because they do not require finding fringe centers and fringe orders. Also, they are accurate. For an active optics experiment in which we have used these techniques, experimental noise exceeds the error resulting from analysis of noise-free theoretical fringe patterns.
