Figure 3 | Comparison with conventional digital image processing architecture. a, Left panel: Schematic representation of the conventional digital-method-based differentiation process. Middle panel: The bright-field image of an onion epidermal cell captured by a commercial microscope. Right panel: The 1st-order differentiation image processed by a digital computer using a Sobel differential operator. b, Left panel: Schematic representation of the metasurface-based simultaneous high-resolution imaging and optical differentiation process. Middle panel: Image of the same onion epidermal cell captured by the metasurface under its 0th-order differentiation mode. Right panel: Image captured by the metasurface under its 1st-order differentiation mode. The red dashed circles in a and b denote the nucleus region of the onion epidermal cell. Scale bars: 20 μm.
