Abstract:	本論文利用橫向剪切干涉術配合稀疏碼，建立考慮訊號密度的低通濾波光學模型。此模型應用於全像儲存系統之記錄端共軛點，以分析全像碟片之紀錄點。依照此模型，能夠模擬不同訊號密度、調製方式及低通寬度下的剪切干涉影像。透過模擬及實驗分析，全像儲存系統之儲存容量，在最高提升為2倍的限制下，至少可以提升為1.368倍。;In this thesis, an optical model considering the density of signal is proposed based on lateral shearing interferometry with use of sparse code through LPF. This model is applied to the conjugate of record side in holographic data storage system for analyzing the record point of the holographic disk. With this optical model, the shearing image in different signal density, modulation mode, filter size can be predicted. In simulation and experiment, the increase of storage capacity is at least 1.368 times by the limitation of twice.
