Abstract
A study of phase multiplexing for volume holographic storage with use of a phase plate of micro-lens array is proposed and demonstrated. We calculate the shifting tolerance of the recorded hologram encoded by a phase plate, which serves as a phase encoder as well as a beam modulator so that high shifting selectivity and high energy efficiency can be achieved at the same time. The experimental results show that a truly-random phase encoding can be performed by the phase plate of micro-lens array.
