摘　　要：分析了体全息存储傅里叶变换光学系统的设计要求和光学参量的确定。采用多重结构方法对傅里叶变换镜头的正向和逆向光路同时进行了优化,可实现对两对物像共扼位置控制像差。给出了前后组焦距分别为44mm和40mm的达到衍射受限要求的4片型球面全息存储光学系统的设计结果。The Fourier-transform （NF） lens applied in volume holographic storage had short focal length. Aberration must be corrected in rather large aperture and little field of view to its positive optical path, and in middling field of view and little aperture to its reverse optical path. The design demand and optical parameter calculation about FT optical system applied in volume holographic storage were analyzed. In order to correct aberration in position optical path and reverse optical path at the ,same time, the multi-configuration method was adopted to optimize the FT lens. A holographic storage FT optical system achieving diffractive-limit is designed. Its front group lens has 44mm focal length, its back group lens has 40mm focal length, and Doth lens consist of 4 piece glass.
