The Performance and Survivability of Dichromated Poly (Vinyl Alcohol) Holograms for Space Based Photonic Applications

Abstract

The results of an experiment which subjected high diffraction efficiency holograms (average: 40%, max. = 58%) written into DCPVA (Dichromated polyvinyl alcohol) photopolymer thin films to the combination of ionizing radiation, temperature and atomic oxygen. This simulated to some extent, the synergistic effects of the LEO (Low Earth Orbital) environment. Remarkably, diffraction efficiency was not found to be significantly degraded in these experiments. A regression model for gamma ray radiation induced degradation in DCPVA holograms is presented. Photopolymer, Dichromated poly (Vinyl Alcohol), Photonics, Photonic memories, Hologram.
