Calculating CGHs needs additional phase-related calculations, elevating computational demands.These calculations can make the development time excessively long or, in the worst case, unaffordable. Our approach, Partial Monte Carlo Sampling (PMCS), calculates CGHs via Monte Carlo techniques. By varying sampling resolution and ray percentages, reasonable quality is achieved, even with fewer rays. Quality analysis employing RMSE and CC reveals that reducing ray percentages does not severely compromise image quality. Both simulated and laboratory holograms display consistent trends, showcasing improved quality with increased rays and resolution. A direct relationship is established between image quality and computational time, addressing specific needs. info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 0.777 2024 Media Technology 2024 Q1 Software 2024 Q2 Computer Networks and Communications 2024 Q2 Hardware and Architecture 2024 Q2 7.7 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Blesa, Alfonso Universidad de Zaragoza (orcid)0000-0001-9688-2260 5008 785 Universidad de Zaragoza Dpto.
