UPDATABLE 3D HOLOGRAPHIC DISPLAY SYSTEM: S-INNOVATION PROJECT'S STRATEGY AND FUTURE PERSPECTIVES

摘要

We present a strategy to achieve an updatable three-dimensional (3D) holographic display system currently developed by our S-innovation project. Photorefractive polymers are promising materials for an updatable 3D holographic display and imaging. Triphenylamine-based photorefractive (PR) polymer composites have a high potential for a holographic display device with the fast response time of 2.2 ms and the high diffraction efficiency of 59 % under an applied field of 60 V μm~(-1). A PR ferroelectric liquid crystal system gave a faster response time of 900 μs and an extremely large optical gain up to 1200 cm~(-1). In addition to these advanced PR composites, PR-like monolithic compound with no-bias field gave great potentials for a 3D holographic diffraction application. Further a molecular designing of PR composites promises an updatable full-color 3D holographic display system.
