[LCTp6-2] Photo-patterned Cholesteric Liquid Crystals for Transparent Computer-generated Waveguide Holography with Visible Playback Capability
Holographic optical elements, Waveguide holography, Cholesteric liquid crystals
A completely transparent waveguide holography in the visible light region is demonstrated based on a photo-patterned cholesteric liquid crystal, which reflects only infrared light. The transparent device also demonstrates that the encoded optical phase information can be coupled out of waveguide mode through visible wave-guided light and observed in free-space.
