A Large Size 3D Holographic Display with PR Polymers

In this STTR project, Boston Applied Technologies, Inc. (BATi), teaming up with Prof. Di Bartolo’s group at Boston College, aims at developing a large size (300 mm x 300 mm) updatable 3D display with photorefractive polymers for battlefield and command and control applications. The proposed 3D display system features fast response (feasible to video-rate), high diffraction efficiency, and relatively low voltage operation. Utilizing a conventional polymeric photorefractive system with an innovative fabrication methodology, the response rate of writing holograms with continuous wave can be raised two orders of magnitude with the diffraction efficiency over 60% to 70 %. Because only one ITO glass plate is used, the total manufacture cost can be lowered, the same for the reflection loss. If pulse writing and erasing beams are chosen, real-timely updating display system is feasible. In Phase I work, we will concentrate on feasibility study of a monochrome 3D display. A prototype of a monochrome 3D display will be implemented in our Phase II efforts.
