Photorefractive Polymers for Updateable 3D Displays

Abstract

During the tenure of this project a large area updateable 3D color display has been developed for the first time using a new co-polymer based photorefractive composite with fast writing times (ms), long persistence (hours) and rapid erasure time (several seconds) (Nature 45, 694 (2008)). In order to enhance the recording speed of the holograms, a recording system with nanosecond pulsed laser having high repetition rate capable of writing the holographic pixel with single pulse was developed and the temporal response of the long-persistence photorefractive polymer composites was optimized to suit single nanosecond pulse exposure. A multi-color recording system was also developed and refreshable color holograms using photorefractive polymers have been demonstrated. Moreover, a 6 inch x 6 inch sample was fabricated demonstrating the feasibility of making large area 3D display devices.
