Abstract

A narrow-angle hyperspectrometer of the visible and near-infrared range (430–900 nm) intended both for detailed aviation monitoring of the Earth’s surface objects and for conducting ground-based research is described. Its angular field of view is four degrees. The sensor operation facilitates the preliminary detection of a small object with another sensor with a large angular field of view, followed by a narrow-angle hyperspectrometer pointing at this object, and its detailed analysis. Ground-based field tests confirmed the operability of the hyperspectrometer in terms of obtaining images of objects with high spatial resolution.
