Multiplexed holograms in phenanthrenequinone–polymethylmethacrylate composite for microscopic applications

The conditions of multiplexed hologram recording in the layers ofpolymethylmethacrylate (PMMA) with a high content of photosensitive components,phenanthrenequinone (PQ), were analyzed theoretically and experimentally. The sequentialrecord of up to 10 holograms onto a single photosensitive layer with a possibility of angularselection of holograms by their reconstruction was realized experimentally. The process ofthe alignment of values of the diffraction efficiency by selecting of exposing dose at eachsequential hologram record was shown. The possibility to use multiplex holograms based onPQ-PMMA layers in application to 3D-microscopy was demonstrated.
