Unit Description

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.

This unit was originally published in September 2019. The revised version is accessible since February 2023. Additional information on this topic can be found in HYPERedu’s Basic MOOC “Beyond the Visible – Introduction to Hyperspectral Remote Sensing”, Lesson 3.
