Abstract

A calibrated phase-shifting digital holography system based on the sampling Moiré technique is proposed. Two synchronized cameras are used in this system. One is to record the conventional holograms that include the object information, and the other is to record the interference fringes to analyze phase-shifting errors. An algorithm for improving the quality of the reconstructed images is proposed. In this Letter, the effectiveness of the proposed system and algorithm is demonstrated in four-step phase-shifting digital holography. The quality of the reconstructed images is greatly improved from both the numerical simulation and experiment.
