Analysis of Recording Conditions of Digital Hologram by Maximum Spatial Frequency
用极值频率法分析数字全息的记录条件

By using holographic theory,hologram sampling theorem and separation condition of frequency spectrum,the maximum spatial frequency of off-axis Fresnel was analyzed,and recording conditions were studied.The expressions of the minimum recording distance and of the parameters of the reference wave were given, which were different from others. Both theoretic analysis and computer simulation show that these expressions gained from this article about off-axis Fresnel hologram are correct and rigorous,but others presented all literatures up to now are not right;only the conditions of sampling and separation are simultaneously met,high quality reconstructing image is gained.
