  • Optical edge detection based on high efficiency dielectric metasurface
    Patent number: 12092790
    Abstract: In some example embodiments, there may be provided a metasurface for edge detection. The metasurface may include a nano or subwavelength surface structure configured to provide an output having optical separation to enable detection of at least one edge of an object being illuminated, wherein the optical separation is based on a phase profile configured on the nano or subwavelength surface structure of the metasurface.
    Type: Grant
