Calibrated phase-shifting digital holography based on space-division multiplexing

This paper proposes a calibrated phase-shifting digital holography by using a single camera. In the proposed system, two types of information are recorded simultaneously in a single image based on the space-division-multiplexing technique. One type of information is used to reconstruct the object image, while the other is used to calculate the phase-shifting amount. As the proposed method can detect the phase-shifting amount accurately without using any additional electronic devices, a simple low-cost high-quality image reconstruction phase-shifting digital holography system can be developed. The effectiveness of the proposed system is demonstrated through experiments.
