• In the design of holographic disc storage system , we first proposed an optimized reflection configuration for sam fourier - transform hologram storage . then we designed and manufactured an asymmetrical fourier transform lens pair , which matched the parameters of slm and ccd and the system requirements . in order to achieve 1 : 1 pixel - matching of high resolution data pages ( 1024 768 ) between slm and ccd , the two lenses were designed and optimized in an iterative manner , and the combination of them reached satisfactory results with eliminated aberrations that can meet the design requirements
  首先提出来用于反射式傅立叶变换体全息存储的空间-角度复用的光路机构,然后按照slm和ccd的光学参数以及系统的工作要求提出傅立叶变换镜头的设计条件,为实现在1024 768幅面的1 : 1像素匹配,设计采用非对称结构的傅立叶变换镜头,可以解决slm与ccd像素尺寸相差比较大的问题,使两个镜头的焦距比同slm和ccd的像素尺寸比相等。
