Latest Patents

One of Zhou's latest patents is focused on flat optics for image differentiation. This innovation features a 2D spatial differentiator that operates in transmission and comprises a silicon nanorod photonic crystal. It transforms an image, Ein, into its second-order derivative, Eα∇E, allowing for direct discrimination of edges within the image. The use of a 2D photonic crystal enables differentiation and edge detection in all directions, achieving a numerical aperture (NA) of up to 0.315 and an experimental resolution smaller than 4 μm. This nanophotonic differentiator can be directly integrated into optical microscopes and camera sensors, showcasing its compatibility with existing imaging systems. Furthermore, integration with a metalens has been demonstrated, leading to a compact and monolithic image-processing system. The nanophotonic differentiator significantly reduces the size compared to traditional systems, paving the way for new applications in optical analog image processing, particularly in computer vision.
