| Abstract: | In this paper we have theoretically deduced the relation between relative diffraction efficiency and rotation angles of the photorefractive crystal with spherical waves as reference and retrieving beams,the equations of diffraction efficiency are numerically simulated and the results of simulation are also analyzed.The results indicate that the storage system with spherical waves has a larger volume,better angular selectivity and is useful for miniaturization of system. |
