Abstract

Permanently photodeformable polymers constitute an interesting class of holographic material, especially for relief holograms used in reflection. We report here preliminary work on a new class of such material which undergoes a controllable change in both thickness and refractive index when exposed to light and then heated. The maximum extent of thickness change is ~30 %, easily giving rise to relief with depth greater than one-half of a wavelength. The holographic efficiency for the first order in reflection then exceeds 25%.
