本文提出一種高效、高品質之影像讀取方式，主要應用於同軸全像光學儲存系統之影像讀取端，其最為特別之處在於對於多階的相位分佈訊號，只需一次的影像讀取便可以讀出影像的相位資訊，並可消除不同像素間的絕對相位差，在縮短影像讀取時間的同時仍可讀出高品質之影像，可以大大提升系統之效能。;This thesis presents an image reading way of highly efficient and high quality, it mainly used in image read of the coaxial holographic optical storage systems. The most special point is, for the multistage phase distribution signal, the image phase information can be read out by just once image reading, and the absolute phase difference between different pixels can be eliminated as well. It has the ability of shortening the time of image reading with high quality, which could greatly promote the effectiveness of the system.
