  • HYPERSPECTRAL IMAGING SYSTEMS
    Publication number: 20230243698
    Abstract: Shortwave infrared (SWIR) hyperspectral imaging (HSI) systems comprise a supercontinuum laser source configured to illuminate objects and a receiver comprising a spectrometer configured to receive light reflected from the objects. In some cases, hyperspectral images can be created by raster scanning of the source/receiver across a scene. The supercontinuum laser source provides active illumination to allow collection of hyperspectral imagery during day (including overcast conditions) and night.
