Abstract

A least-squares fitting technique for the carrier phase component in fringe projection profilometry is presented. The carrier phase distribution for an arbitrary measurement system can be perfectly described with a rational function, whose coefficients can be estimated by least-squares fitting to the measured reference phases, so that the restrictions and limitations in the existing techniques are eliminated.
