Currently, achieving broadband, dynamic, and polychromatic regulation deeply integrated with complex wavefront modulation (such as holography) in a single device remains a significant challenge. The authors of this article propose dynamic polychromatic holography based on the programming of a polymer-stabilized chiral superstructure. Polymer-stabilized cholesteric liquid crystals (CLC), a soft matter chiral superstructure, were used to successfully achieve dynamic polychromatic holographic display with dual multiplexing of wavelength and polarization. This technology is well-suited for applications in high-security dynamic optical anti-counterfeiting, switchable multi-dimensional information display, and high-density optical information encryption/storage systems. Soft chiral superstructure enabled dynamic polychromatic holography.
