Optical analog computing of spatial differentiation and edge detection with dielectric metasurfaces.

Optics Letters, 2020
We propose and demonstrate that optical analog computing of spatial differentiation and edge detection can be realized with a single layer of dielectric metasurface. The optical transfer function for second-order derivation is obtained by engineering the
