Comparison of Multiframe Phase-Shifting Algoritms with Unknown Value of Phase Shift

Original language description

Nonlinear multi-frame phase-shifting algorithms, which use five, six and seven intensity frames to determine phase values in interferometric measurements, are described theoretically. The proposed algorithms compensate for linear phase-shift errors, i.e.miscalibration of phase-shift, which are very common in practice of interferometric measurements. The phase-shift value is assumed unknown but constant in these algorithms. An advantage of the described algorithms is a possibility of pointwise phase-shift calculation
