Three-dimensional profilometry based on two-step generalized phase shift for phase measurement of grating projections
An algorithm is proposed to extract the phase from deformed grating images using a two-step generalized phase-shifting technique for fringe projection profilometry (FPP). This method is based on the principle of the least squares iterative method, which directly extracts unknown phase shift from two...
