A Novel DMD Display of Phase-Only Coding Hologram

In order to reduce the complexity of hologram generation and holographic display, for the first time the paper combines Gerchberg-Saxton iterative algorithm with Lohmann coding to make phase-only hologram and designs a digital micromirror device (DMD) display system. Thus we not only solve the problem that the amplitude of the frequency spectrum of object function fluctuates very greatly but also avoid the complicated process for producing hologram produced by the plotter, which is controlled by computer. And by this method we can further avoid the complicated technology by etching silicon crystal and improve the quality of imaging.
