Abstract

A variety of environmental exposure tests were conducted on holographic optical elements. Previous reports from our lab have largely been confined to studies on simple mirror holograms in unconverted format. This study was expanded to include slant-fringe diffuse reflectors as well as normal- incidence simple mirrors converted into commercially practical formats with adhesives and different types of support substrates. Holograms were characterized using reflectance as well as transmission spectroscopy. Films were subjected to 30 cycles of 80 degree(s)C to -30 degree(s)C air-to- air temperature cycling, 14 day 70 degree(s)C/95% RH hold, 14 day 100 degree(s)C dry heat hold, 540 hour continuous ultraviolet exposure, and 14 day cycled fluorescent roomlight exposure. Playback wavelength and diffraction efficiency was stable under all conditions. As reported earlier, exposure to intense ultraviolet light increases yellowness of the photopolymer holograms, but this can be prevented by laminating a UV-absorbing layer atop the film.
