Absolute Depth Measurement Using Multiphase Normalized Cross-Correlation for Precise Optical Profilometry

In a multifrequency phase-shifting (MFPS) algorithm, the temporal phase unwrapping algorithm can extend the unambiguous phase range by transforming the measurement range from a short fringe pitch into an extended synthetic pitch of two different frequencies. However, this undesirably amplifies the u...
