Dealing with systematic laser scanner errors due to misalignment at area-based deformation analyses
(2018-03-07)
The ability to acquire rapid, dense and high quality 3D data has made terrestrial laser scanners (TLS) a desirable instrument for tasks demanding a high geometrical accuracy, such as geodetic deformation analyses. However, ...
Improved area-based deformation analysis of a radio telescope’s main reflector based on terrestrial laser scanning
(2015-03-14)
The main reflectors of radio telescopes deform due to gravitation when changing their elevation angle. This can be analyzed by scanning the paraboloid surface with a terrestrial laser scanner and by determining focal length ...
