Abstract: Image hologram is analyzed and comprehended from a new point of view - microcoding patterns of elementary hologram in the paper. The elementary microcoding patterns of image hologram are quantitatively discussed using the elementary analysis method. The mathematic models of the spatial interference patterns of elementary image hologram are established, and the interference fringe patterns on recording plane are studied qualitatively. The purpose and significance of the study is to establish the information coding relationship between the spatial object information (especially position information) and the interference fringe patterns on recording plane correspondently. By analyzing the macroscopic physical meanings of the structural characteristics of interference patterns, the recording and reconstruction mechanism of image hologram are probed deeply into microscopic field.!2
