Full-color multiplexed reflection hologram of diffusing objects recorded by using simultaneous exposure with different times in photopolymer Bayfol® HX 2021 Access copy available to the general public Unrestricted An optimized wavelength multiplexing procedure for color reflection holograms of diffusing objects recorded in Bayfol® HX photopolymer is proposed. It is based on simultaneous initial illumination of all the wavelengths and sequential shuttering down of the laser beams involved. Three lasers of 442 nm, 532 nm and 633 nm were selected, as a tradeoff solution between setup complexity and color reproduction accuracy. The obtained results prove that the presented method improves the simultaneous and sequential exposure methods by increasing the mean efficiency and reducing the standard deviation (increasing uniformity) of the involved wavelengths. For a Spectralon® diffusing object, the assessed method reports a mean efficiency of 25.0% with a standard deviation of 2.9%, while simultaneous and sequential iterative exposures result in mean efficiencies of 12.1% and 20.6% with standard deviations of 3.4% and 5.4%, respectively. info:eu-repo/grantAgreement/ES/DGA/E44-17R info:eu-repo/grantAgreement/ES/MICINN-AEI/PID2019-108598GB-I00/AEI/10.13039/501100011033 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 4.939 2021 PHYSICS, APPLIED 39 / 161 = 0.242 2021 Q1 T1 OPTICS 20 / 100 = 0.2 2021 Q1 T1 0.848 2021 Electrical and Electronic Engineering 2021 Q1 Atomic and Molecular Physics, and Optics 2021 Q1 7.6 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Marín Sáez J.
