ABSTRACT
In this paper, the methodology of research of the 32-meter radio telescope RT-4 antenna dish measurement belonging to the Institute for Astronomy at Nicolaus Copernicus University in Torun, placed in Piwnice is presented. The measurements were carried out using terrestrial laser scanning technology. Analysis of the results is carried out to determine the deformation of the radio telescope antenna dish with the determination of the impact of external factors on the studied phenomenon. Research described in the article are adopted to the research methodology as well as describe the first measurement session already realized with the preliminary analysis of the data. Ultimately, the study relate to compare methods of measurement using terrestrial laser scanning technology with the holographic method of antenna dish radio telescope measurement in terms of accuracy of results and efficiency of methods is presented. Such a comparison will be the first example of a previously completed joint use of both techniques and innovative way of approach to determine the deformation of the radio telescope antenna dish.

Keywords: radio telescope, terrestrial laser scanning, holography, deformation
