摘 要：The overall goal of this program was to develop a large area updateable 3D color display using unique and innovative photorefractive (PR) polymers with fast writing times (ms), long persistence (hours) and rapid erasure (several seconds). A multi-pronged approach was used to integrate the presently established materials, find new photorefractive materials, and electronics and photonics techniques to achieve the following goals: (1) 3D display devices: we developed large area PR polymer devices for updateable 3D display; (2). Materials optimization: we designed and synthesized a PR polymer with high figures of merit for 3D display applications; (3) Nanosecond pulse recording: recording setups based on a high repetition rate nanosecond pulsed laser to increase the recording speed were developed; (4) Color holograms: A color 3D display system was implemented by angular multiplexing.
