Principle and Physics of the LiDAR Measurement
Résumé
In this chapter, a brief overview of the LiDAR measurement used for Earth and space observation is first presented. This is subsequently followed by an overview of the LiDAR instrument, describing its various optical constituent elements. The LiDAR equation is then described with emphasis on its key parameters. Finally, the main causes of LiDAR error on surface observations are specified, with a particular emphasis on airborne or spaceborne measurements.
