title = "Using the Resolution Capability and the Effective Number of Measurements to Select the “Right” Terrestrial Laser Scanner",
abstract = "The point-to-point distance, the spot size and its shape limit the minimum size of objects that can be spatially resolved in a TLS point cloud. As the laser beam has a footprint of at least a few millimeters, adjacent laser spots overlap if the sampling interval is chosen small. Thus, they do not provide individual information about the object surface and they are correlated. To evaluate the performance of different terrestrial laser scanners to resolve small objects spatially, we investigate their resolution capabilities. Our results show that the expansion and the magnitude of the resolution capability vary between the scanners due to the different focusing and shape of the laser beam, and the rotational speed of the deflecting mirror. Furthermore, we use the resolution capability to assess which scanner provides the most uncorrelated information. Thus, this study provides a measure to judge the scanners{\textquoteright} usability for specific applications, such as finding a crack in a wall.",
