Characterization of imaging spectrometers

The increasingly widespread applications of the Earth observation system information and the rapid development of modern technologies over the past decades have led to the imposition of remote sensing tools and, in particular, of the imaging spectrometers. These trends place high demands on the development and improvement of both the systems themselves and the characterization methods. This paper highlights features that are expected to be considered critical for imaging spectrometer performance: The basic steps for characterization of imaging spectrometer critical characteristics are indicated in the flow diagrams. The characterization methods and correspondence correction procedures are determined and the obtained results are presented.
