Metasurface‐Encoded Single‐Pixel Hyperspectral Imaging

open access: yesAdvanced Photonics Research, EarlyView.
A metasurface‐enabled single‐pixel hyperspectral imaging approach is proposed, achieving sub‐2‐nanometer spectral discrimination and accurate reconstruction at low sampling ratios. By uniting advanced nanophotonics with data‐driven algorithms, this framework overcomes limitations of conventional single‐pixel imaging and sets a new benchmark for compact
