Design of Interactive Meta-holographic Display using Liquid Crystallinity

Abstract

Liquid crystals have been widely used to design reconfigurable materials that sense external stimuli and modulate properties of light. Here, we propose general and versatile approach to enable active metahologram by integrating the thin layer of stimuli-responsive LC layer into multiplexing-metasurfaces. We demonstrate the new class of metahologram can dynamically change homographic images in response to a programmed stimulus (e.g. electric field, heat, pressure and toxic gas).
