A metasurface-based imaging system, a design method, and a detector. In an optical axis direction, the metasurface-based imaging system sequentially comprises: a quadratic-phase-based metasurface structure, consisting of a sub-wavelength unit structure array () and a substrate (), the metasurface structure being a monolayer structure and used for implementing preset phase distribution; and a wavevector filter (), each position of which is equivalent to one aperture stop, the wavevector filter having a filtering function and having different wavevector modulation effects under different incident angles. The metasurface-based imaging system has the advantages of being ultra-light, ultra-thin, and high in imaging quality, and can achieve large-area, ultra-thin, and large field-of-view imaging detection.
