Remote sensing acquires and interprets small or large-scale data about the Earth from a distance. Using a wide range of spatial, spectral, temporal, and radiometric scales remote sensing is a large and diverse field for which this Handbook will be the key research reference. Illustrated throughout, an essential resource for the analysis of remotely sensed data, The SAGE Handbook of Remote Sensing provides researchers with a definitive statement of the core concepts and methodologies in the discipline.

Introduction

Imaging spectrometers have significantly improved the understanding of interactions of photons with the surface and atmosphere. Spectroscopy has existed since the eighteenth century; the imaging part of this term became technically possible in the early 1980s. The first part of this chapter is devoted to a short historical background of this evolution. In subsequent sections, imaging spectroscopy is defined and the main acquisition principles are discussed. The main imaging spectrometers used for Earth observation are presented, as well as emerging concepts which give an insight in a broad range of air to spaceborne associated technology. Imaging spectroscopy has expanded to many other disciplines, and the approach is used in medicine, extraterrestrial research, process, and manufacturing industries, ...
