Paper Abstract

C.I.E. chromaticity diagram has been used as a mean that permits to associate standard visual color perception with several interesting physics quantities: Temperature, characterization of lighting sources, thickness of thin films, and the amount of material in alloys and paintings. In specific, who works in interferencial microscopy knows the relation between isocolor curves, which are produced in a white light interferogram and the topography of the object under observation. A study about locus of these colors into the Chromaticity diagram is done in this work. Colors are produced by interference among plane wave fronts of white light with different delays. By this study, standard clibration that permits to extract topography information from some real interferograms can be obtained.
