Abstract:

This paper discusses relief scanning carried out by overhead laser scanners. It is shown that the relief-frequency response is needed in order to represent the scanning accuracy. A definition is introduced, and a technique is given for measuring the relief-frequency response of a laser scanner. Equations are obtained that determine the lidar pulse frequency needed to provide a specified sampling density. It is shown that a multibeam laser-radiation structure can be used to increase the sampling density when scanning relief.
