Twofold optical display and encryption of binary and grayscale images with a wavelength-multiplexed metasurface
The remarkable capability in regulating light polarization or amplitude at the nanoscale makes metasurface a leading candidate in high-resolution image display and optical encryption. Diverse binary or grayscale meta-images were previously shown concealed in a single metasurface, yet they are mostly...
