Optical metasurface technology, a novel planar optical technology, has made great progress in recent years, opening up broad application prospects for optical imaging. Metasurfaces offer several advantages, such as multifunctionality, easy integration, lightweight design, and compactness, while precisely controlling the wavefront. These innovative benefits provide new possibilities for multidimensional light field imaging technology and metasurface-based computational imaging. Metasurfaces can also be used in cutting-edge applications, such as augmented reality (AR), virtual reality (VR), optical fibers, and optical waveguides. They are also instrumental in innovative imaging technologies like super-resolution and quantum imaging. In the future, metasurfaces are expected to exhibit greater flexibility and adaptability, meeting the needs of various complex application scenarios and playing an increasingly important role in the field of optical imaging.
