Paper Abstract

Phase shifting error is a major error source in phase-shifting digital holography. It affects the quality of the reconstructed object and causes errors in its phase and amplitude calculation. This paper presents a simple method to accurately retrieve the actual phase-shifting value used in practical hologram recording. It therefore provides the possibility of completely eliminating the phase-shifting error in digital hologram. The proposed method is based on solving the object wave reconstruction equation. The effectiveness of the proposed method is verified by both mathematical analysis and computer simulation.
