Metamaterials and metasurfaces are novel optical components composed of nanostructure arrays. They offer the advantage of an ultracompact form factor and can image submicron objects with resolution approaching the diffraction limit of light. The scope of this imaging extends from simple microscopes to more advanced light imaging applications such as 3D sensors, LiDAR, bio-imaging, and cameras. The wavelength range of imaging is also diversifying to support various imaging applications. Metalenses operating in the UV region enable high-resolution imaging due to the short wavelength of light. In the visible light spectrum, metalenses can be used for imaging in VR/AR displays.
