Laser scanning – principles and applications

In this overview paper the principles of laser scanning systems are presented.<br>This includes a survey of different range measurement principles as well as different<br>mechanisms for the deflection of the emitted laser beam. Furthermore, the usage of the<br>laser scanning (LS) principle at different platforms (airborne (ALS), terrestrial (TLS),<br>satellite) is discussed. Additionally, typical sensor parameters of currently commercially<br>available sensor systems are presented. Furthermore, the technique of full-waveform LS<br>is introduced and georeferencing of ALS data for improved precision is presented. The<br>usage of LS data in different applications will be presented in an overview.
