摘要

A single-lens implementation of optoelectronic spatial frequency filtering for incoherent illumination is demonstrated utilizing metasurface engineering. By inverse-designing the phase on the metasurface, arbitrarily structured 2D filters are realized for depth-invariant, broadband operation. (C) 2021 The Author(s)
