  • Publication number: 20240312369
    Abstract: A metalens, a metalens set, and a method of image construction or decryption are disclosed. The metalens includes metastructures each having a shape and a height related to a resonant light wavelength of the metastructure, so that the metalens can present an incident light of the resonant light wavelength as a light shape or light pattern at a far-field position matching the resonant light wavelength. A metalens set formed by staking the metalenses vertically can present incident lights having different resonant wavelengths as light shapes, light patterns, or resolved images at far-field positions matching the resonant wavelengths. Image construction or decryption are achieved by combining resolved images of the resonant light wavelengths with non-resolved images of non-resonant light wavelengths so as to compose an overlay image, which is to be decomposed by the metalens or the metalens set so as to recover the resolved images.
