Caption

a, LC-based vectorial holographic clock for time information encryption. b, Target holographic images for incident light with RCP, LCP, and LP. The corresponding vectorial information is denoted. c, Simulated phase difference distribution between the holographic images of LCP and RCP. d, POM texture of the holographic LC superstructure. Scale bar: 50 μm. e, Vectorial LC-holographic images at various input/output polarization channels. The measured Stokes parameter values of four typical regions in the LC-holographic clock image are presented at the bottom.
