In this article, a holographic display method based on complex wavefront modulation using single spatial light modulator is proposed, which is achieved from complex wave front encoded by double phase hologram.Abstract:
A holographic display method based on complex wavefront modulation using single spatial light modulator is proposed. The holographic display is achieved from complex wavefront encoded by double phase hologram. The modulated beam by single phase-only spatial light modulator passes through a 4f optical system to synthesize the expected complex modulated wavefront on the output plane, with a low-pass filter in the Fourier plane. The performance of holographic display is also improved by complex wavefront modulation, compared with the holographic display based on phase-only wavefront modulation. The proposed encoding and display technique is theoretically demonstrated, as well as validated in numerical simulations.read more

Experimental Aspects of Holographic Projection with a Liquid-Crystal-on-Silicon Spatial Light Modulator
TL;DR: In this paper, the differences between the behavior of the modulator as expected from Fourier optics and that observed in practical optical experiments are discussed, and practical hints and proven techniques of overcoming selected hardware issues of the chosen liquid-crystal-on-silicon (LCoS) phase modulators are given.
