Abstract

In-line digital holography using a random phase modulation is proposed. Owing to the random phase modulation, twin-image problem inherent to the in-line optical setup is relieved. Furthermore, because no multiplexed recording is required, dynamic phenomena can be recorded. This idea is inspired by double-random phase- encryption. The difference between the proposed method and the double-random phase-encryption is brie y described. Preliminary experimental results confirm the feasibility of the proposed method. The difference of coherence of a light source is also discussed.
