Multiplexed holograms recorded in a low toxicity Biophotopol photopolymer

Multiplexed diffraction gratings were recorded in 300 μm thick layers of Biophotopol photopolymer by using peristrophic multiplexing schema. Thirteen sinusoidal phase gratings were stored in a low toxicity recording medium. The diffraction efficiency conservation of the multiplexed diffraction efficiency obtained was studied along the time.This work was supported by the Ministerio de Economía y Competitividad (Spain) under project FIS2014-56100-C2-1-P and FIS2015-66570-P and by the Generalitat Valenciana (Spain) under projects PROMETEO II/2015/015
