Abstract: |
In this paper,the recording and readout characteristics of photorefractive volume hologram were studied by using Fe:LiNbO3 crystal as the recording medium.The optical experimental setup for angular multiplexing photorefractive volume holographic was constructed in which several photorefractive holograms were recorded.The response sensitivity of Fe:LiNbO3 crystal was studied by experiment.The diffraction efficiencies of photorefractive volume hologram in holographic recording and readout stage were measured.Besides,the minimum interval in angle multiplexing hologram was measured.The results of those measurements would contribute to evaluate and optimize the capacity of angle multiplexing hologram. |
