【摘要】 提出和设计了一种应用于体全息存储系统的傅里叶变换透镜,是为了适应体全息存储系统对傅里叶变换透镜的特殊要求而设计的。设计中使用了光学自动设计软件ZEMAX。综合各方面考虑,采用双平凸结构,具有以下特点:焦距短,系统结构紧凑;焦距易于改变,以方便实现不同焦距比;工作视场大,能提高体全息存储系统的存储密度;结构简单,容易加工装调,造价低。透镜组用于像素数为1k×1k的空间光调制器(SLM)与CCD匹配对准。更多还原

【Abstract】 A kind of Fourier transform lenses applied in the volume holographic data storage system (VHDSS) is presented. It is designed to meet the special need of the VHDSS for the Fourier transform lenses. An optical automatic design software ZEMAX is used in the procession. After compromise, the structure is designed to be the double convex-plan. The lens has many advantages: simple structure, easy fabrication and low cost; changing the focal length (FL) easily, achieving different FL ratio conveniently; short FL and compact system structure; large field range increasing the storage density of VHDSS. The lens can be applied in registration between the 1k×1k spatial light modulator(SLM) and CCD in the VHDSS.更多还原
