Direct Fringe Writing of Computer-Generated Holograms

Groups

Photorefractive polymer has many attractive properties for dynamic holographic displays; however, the current display systems based around its use involve generating holograms by optical interference methods that complicate the optical and computational architectures of the systems, and limit the kinds of holograms that can be displayed. We are developing a system to write computer-generated diffraction fringes directly from spatial light modulators to photorefractive polymers, resulting in displays with reduced footprint and cost, and potentially higher perceptual quality.
