Decomposition and compensation of fringe harmonic errors by use of their partial orthogonality in phase-shifting fringe projection profilometry

In phase-shifting fringe projection profilometry, fringe harmonics have been recognized as one of the main error-inducing factors. Generally, the response of a phase-shifting algorithm to fringe harmonics strongly depends on the used phase shifts and is usually unpredictable, especially when using n...
