Abstract

We demonstrate an optical image processing technique in the form of edge detection of an object by exploring the angular selectivity of Mie-resonant dielectric metasurfaces of hexagonal symmetry. We examine the effect of both electric and magnetic Mie-type resonances on the spatial dispersion and reveal that the magnetic resonance provides better edge detection. We also explore the polarization sensitivity of the edge detection process and show that edge detection in our hexagonal metasurface is polarization independent. Our results shed light on the underlying mechanisms of edge detection with resonant dielectric metasurfaces and open new opportunities for ultracompact optical image processing devices having multiple applications in vision and microscopy.
