Multiplexed holograms recorded in a low toxicity Biophotopol photopolymer

摘要

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.
