Paper Abstract

We have developed holographic diffusers that provide achromatic forward scattering with low backscatter and absorption, even at large scattering angles. The angular scattering pattern may be highly asymmetric in the azimuth and elevation directions, and may also be skewed away from the incident beam. Volume phase holographic diffusers recorded in dichromated gelatin exhibit particularly low backscatter and absorption, and also exhibit the unique property that the output lobe in some configurations does not move with the input ray angle. These diffuser properties allow the fabrication of efficient, uniform backlights for LCD displays in aircraft cockpits.
