| Description | A wavelength multiplexing procedure for color transmission volume holograms of diffusing objects recorded in $Bayfol^{®}$ HX200 photopolymer is proposed. For the recording, three lasers of 442 nm, 532 nm and 633 nm, and a $Spectralon^{®}$ diffusing object were used for monochromatic and polychromatic calibration. Monochromatic calibration shows that the maximum index modulation obtained for each wavelength was not enough to give 100% efficiency, although the efficiency values achieved in the case of monochromatic recordings with diffusing objects were high, at around 90% for 633 nm and 532 nm recordings, and 60% for 442 nm. The efficiency values obtained for multiplexed holograms were 19.1% for the 442 nm hologram, 25.9% for the 532 nm hologram and 15.2% for the 633 nm. |
