Abstract: An array of cascaded metasurfaces implements a compact and lightweight spectral imager that acquires real-time videos. Spectral imagers divide scenes into quantitative and narrowband spectral channels. They have become important metrological tools in many areas… read more here.

Abstract: We propose a snapshot spectral imaging method that enables direct reconstruction of spatial maps for spectral signatures of given materials using a monochromatic image sensor. An image-plane array of dispersive shapers converts an aerial image… read more here.
