This unit introduces the physical background related to imaging spectroscopy. The basic laws of electromagnetic radiation are addressed. Based on that, processes of radiation transfer as well as radiation – atmosphere – target interaction are characterized. Lastly, several example spectra of various surface materials are presented and interpreted.
