title: Phase-stepping automatic fringe analysis in holographic moiré.
abstract: The phase-stepping technique is used to analyze holographic moiré patterns. This new application permits the instantaneous determination of phase functions in both moiré and carrier fringes. Two modified phase-stepping self-calibrating techniques are proposed and demonstrated on computergenerated noisy moiré patterns. The techniques do not complicate the holographic moiré arrangement and do not need auxiliary carrier fringes. A holographic moiré interferometer that has been adapted for these phase-stepping techniques is proposed.
