Abstract
101 volume phase holograms are recorded at 514.5 nm by superposition in a 2.6 mm thick block of the polymeric system PMMA/MMA/Titanocenechloride. The sample has been rotated 0.1° between recordings. All volume phase holograms can be read out individually at the corresponding Bragg angles due to the high degree of angular selectivity in a thick storage medium. The holographic recording proceeds irreversibly. Hence a holographic “write once — read only memory” with very large storage capacity can be realized. The multiple storage capability of this optical recording medium is investigated experimentally.
