Phase-coded multiplexing using a crossed cylindrical-collimating lens system for volume hologram storage in LiNbO_3

摘要

We propose a phase-coded multiplexing method that employs the rotation of a crossed cylindrical-collimating lens system to encode the reference beam of each multiplexed hologram for volume hologram storage. This phase coding scheme is compared with that based on random phase-coded multiplexing. Our experimental results demonstrate that the method can simplify the procedures of recording and reading in hologram storage.
