Monolithic metasurface spatial differentiator enabled by asymmetric photonic spin-orbit interactions

Spatial differentiator is the key element for edge detection, which is indispensable in image processing, computer vision involving image recognition, image restoration, image compression, and so on. Spatial differentiators based on metasurfaces are simpler and more compact compared with traditional...
