The reconstructed image of a SPOH is a sparse image with abundant empty voids and degradation in sharpness and contrast. In this paper we proposed a method based on a new sampling scheme, together with stochastic binary search (SBS), to obtain an optimal sampling lattice that can be applied to generate phase-only holograms with enhanced reconstructed image. Experimental results show that with our proposed method, the fidelity and quality of the reconstructed image are increased.Pages 25488-2549811 page(s)application/pdfenIn CopyrightOpticsGENERATIONPROJECTIONALGORITHMIMAGEOptics0205 Optical Physics0906 Electrical and Electronic Engineering1005 Communications TechnologiesArticle - Refereed2022-02-15https://doi.org/10.1364/OE.4307762916Poon, Ting Chung [0000-0002-7070-6856]346148791094-4087
