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 are presented. 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.
