A digital micro-mirror device (DMD) has the potential to modulate an incident wave with high speed,and the application for holographic display has been studied by many researchers. However, the qualityof reconstructed image isn’t good in comparison with that from a gray-scale amplitude-only hologram sinceit is a binary amplitude-only spatial light modulator (SLM). In this paper, we suggest a method generatinga set of binary holograms to improve the quality of the reconstructed image. Here, we are concerned withthe case for which the object plane is positioned at the Fourier domain of the plane of the SLM. In thiscase, any point in the Fourier plane is related to all points in the hologram. So there is a chance to generatea set of binary holograms illuminated by incident wave with constant optical power. Moreover, we findan interesting fact that the quality of reconstructed image is improved when the spatial frequency bandwidthof the binary hologram is limited. Therefore, we propose an iterative segmentation algorithm generatinga set of binary holograms that are designed to be illuminated by the wave with constant optical power.
The feasibility of our method is experimentally confirmed with a DMD
