One of the interesting applications of white-light optical signal processing must be psuedocolor encoding. In this paper, we will demonstrate some of those applications to holographic interferometric and metrological studies. Techniques of producing pseudocolor encoded holographic fringe patterns and misfocused speckle interferograms are provided. These techniques allow the viewing of a multiset of encoded interferograms simultaneously. Talbot interferometric technique for pseudocolor encoding phase object and depth utilizing a white-light processor is also presented. The white-light optical processing technique offers the simplicity, versatility, and cost effectiveness in the application to interferometric and metrological studies.
