An optically rewritable/reconfigurable patterning method is reported. Circularly polarized (CP) light is employed to write information into cholesteric liquid crystal cells fabricated with a photoaligning boundary layer. Macroscopic scattering areas, patterned via CP light, can be reconfigured into a new pattern by erasing (i.e., returning cell to reflective state) with linearly polarized (LP) light and writing a new pattern with CP light.
