Abstract

Photorefractive crystals are very attractive materials for volume holographic memories. For the angular multiplexed holographic memory, many holograms are recorded in the crystal with changing the incident angle of the reference beam. In this paper, we report a novel sensing-recording device using a photorefractive crystal, which is the combination of the optical sensing device on a concept of an angular multiplexed holographic memory, for nondestructive surface inspection
