Abstract

Phase-shifting property of moire patterns which constitute spatially sampled data set of single interferograms with a linear carrier is revealed. Based on this property, a phase reconstruction method using the phase-shifting algorithm is proposed for single interferograms with a linear carrier. Limits of a carrier frequency and a phase slope being reconstructed are given.
