  1. Chapter 4 : the influence of different phase - shifting angle of reference wave in recording, of the phase - shifting error and of the quantization error on the quality of the reconstructed image is investigated respectively in two - step phase - shifting inline digital holography. and an effective method of eliminating the phase - shifting error is presented, in which the summation of the intensity bit errors of the reconstructed image is taken as an evaluation function for an iterative algorithm to find the exact phase - shifting value. the feasibility of this method is demonstrated by computer simulation

    通過數值分析不同相移角的選取對再現像的強度誤差的影響，發現再現像強度誤差依賴于記錄時相移角的選取，當相移角在一定范圍內，其再現像的強度誤差相對較小；提出了一種有效消除相移誤差的新方法，並將其應用於二步同軸相移數字全息，對此進行了計算機模擬，得到了很好的結果，證明該方法對于相移誤差的消除是很有效的；對量化誤差所作的數值模擬發現，當信號被量化成8比特（ bit ） ，即256個灰度級以上，量化噪聲的影響相對較小。
  2. Therefore, computer - generated hologram and digital holography has been developed consequently

    因此，相繼產生了計算全息和數字全息技術。
  3. This paper is trying to combine computer - generated hologram and digital holography together, to give the stimulated algorithm of the fresnel diffraction and through computational stimulation generate the hologram, which will reconstruct the original image, and ultimately, realize the numerical reconstruction of the hologram

    本文嘗試將計算全息與數字全息相結合，研究光線的菲涅耳衍射傳播的模擬演算法，用計算機模擬生成全息圖，並由所生成的全息圖再現出原始圖像，實現全息圖的數字重現。
  4. Digital holography is a novel imaging technique which uses high - resolution ccd - cameras as hologram recording medium and reconstructs the image with numerical method. it involves optical holography, computer science, electronic technology and digital image processing. in recent years, particle analysis with digital in - line holography is an active research field
