摘　　要：针对光学全息再现像质较差,本文提出四片式近似全对称傅里叶变换透镜的设计。该设计根据电寻址液晶和CCD对傅里叶变换透镜的匹配要求确定设计参数。为了缩短总长,系统采用双远距结构,并利用ZEMAX自动设计软件进行优化设计。将设计结果应用于实验,获得了清晰的光学全息再现像。实验结果表明,该设计的各项指标与实验系统相匹配,具有结构简单,像质好,满足较大孔径和视场要求等优点。A design of Fourier transform lens which adopt four-approximate symmetric structure was designed based on poor quality of optical holographic reconstructed image. The lens parameters were determined by the matching requirements of Electrically Addressed Liquid Crystal Displays （EALCD） and CCD. A double long-range structure was adopted in order to decrease total length, and optimized by ZEMAX of auto designed software. The designed result had been applied to the experiment and clear optical holographic reconstructed images were obtained. The experimental result indicates that each index of the Fourier transform lens has matched the holography system and has many advantages, such as simple and compact structure, cheap material and high-quality imaging.
