Two methods for color coding of phase variations of an object in coded correlation filtering quasi-interferometry are introduced. One is based on dispersive filtering, the other on color correlation filtering with colored masks. Performances are analyzed in terms of geometrical optics. Various possible configurations are studied. Experiments have proved its usefulness in practice. The phase variation can be measured to a high degree of precision if a spectroscopic measurement is made.
