( 2 ) the reconstruction of image plane hologram is analyzed by plane wave theory. the image plane holograms of transparent and opaque objects are also obtained by using fibers

    （ 2 ）用角譜理論分析了像面全息圖的再現過程，採用光纖傳光分別拍攝了透射和反射物體的像面全息圖，並利用頻域法對全息圖進行數值再現，得到了物體較清晰的再現像。
  3. 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

    首先提出來用於反射式傅立葉變換體全息存儲的空間-角度復用的光路機構，然後按照slm和ccd的光學參數以及系統的工作要求提出傅立葉變換鏡頭的設計條件，為實現在1024 768幅面的1 : 1像素匹配，設計採用非對稱結構的傅立葉變換鏡頭，可以解決slm與ccd像素尺寸相差比較大的問題，使兩個鏡頭的焦距比同slm和ccd的像素尺寸比相等。
  4. In order to investigate the phenomenon that holograms tend to be deteriorated on baing recorded in photopolymers with shrinkage, a fourier hologram is taken with slant gratings formed by the reference beam and object beams of different space - frequency

    摘要為了分析光致聚合材料記錄的譜面全息圖在再現過程中發生「擦除」現象，將譜面全息圖看作由不同角譜的物光與參考光在光致聚合材料內形成的不同傾斜角度的光柵總和。
