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。 -
