Estimation of Focal Length Variations of a 100-m Radio Telescope's Main Reflector by Laser Scanner Measurements
(2012-08)
Due to gravitation, the main reflector of a radio telescope underlies a deformation which causes
a change in focal length depending on the variations of the elevation angle of the telescope. In order
to estimate these ...
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 ...
