Abstract
In this paper, we demonstrate a method for random phase optimization in the Fresnel domain that enables the fast generation of phase-only holograms (POHs). Our proposal consists of applying the iterative Fresnel transform algorithm (IFrTA) to optimize a random phase with the parameters of a given holographic projection system. Then, the resulting optimized Fresnel random phase is used for the generation of POHs of several objects. We compare the performance of our proposed method to the direct generation of holograms using IFrTA, and quantitatively study the quality of the reconstructed object varying the generation parameters. Our results show significantly improved computation speed and minor loss of accuracy compared with the direct application of the IFrTA. We present both numerical and optical reconstructions obtained with a holographic projection scheme based on a phase-only spatial light modulator to verify the validity and effectiveness of our proposal.
