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.
