Abstract

In this paper, a novel method for holographic projection is presented. SLMs are employed to modulate incident light beams and reconstruct the output image by interference. There is a great advantage of this novel method that the algorithm for calculation the phase patterns on SLMs does not need iterative process, which is greatly computationally efficient and hence provides a possibility to achieve real-time video holographic projection based on standard PC hardware. Two holographic-projection architectures for this novel method are proposed. Simulation results demonstrate the validity of this new proposed method. It is believed that this technique is useful in further real-time video holographic projection.
