A fringe pattern represents an encoding of spatial information. A means is developed to create the fringe pattern based on a method to encode the spatial variations. This paper considers fringe patterns created by the interference of optical wavefronts with spatial extent, thus representing the spatial variation of optical path difference between two interfering optical waves. How the fringe pattern is created, the selection of the interferometric methods, adds value to the quality of the fringe pattern (the quality of the information encoded in the fringes), but the results, the analysis of the fringe pattern is where the user (customer) derives value.
