Title:
METASURFACE SPARSE APERTURE LENS
Document Type and Number:
WIPO Patent Application WO/2021/077485
Kind Code:
A1
Abstract:
A metasurface sparse aperture lens (101), comprising a plurality of sub-lenses (102) arranged in a certain sequence; each sub-lens (102) comprises a plurality of microstructures (103) and a substrate (104) supporting the microstructures (103), and all of the sub-lenses (102) jointly form a metasurface sparse aperture lens (101). Phase information corresponding to the metasurface sparse aperture lens (101) may be determined by the wavelength of incident light and the focal length of the lens. By using sparse aperture technology, the same spatial resolution as a large-aperture optical system may be obtained by means of an array system of the sub-lenses (102), thereby reducing the difficulty of preparation and processing costs of a large-aperture super lens (101). The present invention has high application value in the miniaturization and integration of microscopic imaging systems and endoscopic imaging systems and like aspects.
