Paper Abstract

Hyperspectral imaging divides a scene into many spectral channels with narrow spectral width. Here we present a compact hyperspectral imaging system based on dielectric metasurfaces. Our system has nine channels spanning 795 nm to 970 nm, which are arranged in a rectangular array and acquired in a single snapshot, in contrast to many commercial systems. The system's narrowband filters, necessary for hyperspectral operation, also reduce chromatic aberration, a common problem in metasurface imaging systems. The small footprint of the device (2.5 mm × 2.5 mm × 1.5 mm) facilitates its potential integration into a handheld system (e.g., a mobile phone).
