Characterizing the performance of meta-imager for convolution operation

Caption

(a) Working principle of meta-imager for arbitrary convolution operation; (b) Edge detection of (b) amplitude objects and phase objects and (c) DNA molecules. (d)Spatial differentiation for removing directional defects in onion epidermal cells. (e) Denoising for eliminating random noise of oral epithelial cells. (f) Characterization of edge detection by using the singlet meta-imager where the distance between the metalens and the meta-modualtor is zero.
