Design and Analysis of Quasioptical
Components for use in Astronomical
Telescopes.
Masters thesis, National University of Ireland Maynooth.
Abstract
This thesis describes the use of Gaussian beam modes (GBM) and physical optics
(PO) to design and analyse astronomical telescope systems operating at millimetre
and submillimetre wavelengths. The techniques are applied to a proposed re-design
of the 3 mm channel of the 20 m Onsala Space Observatory telescope. The industrystandard
software GRASP was used for the PO simulations; GBM analysis was
carried out using code written in mathematical software packages. GRASP was used
to investigate the effect of random and systematic surface errors on such systems.
Finally, Maynooth University's Vector Network Analyser was calibrated, aligned
and used to characterise new waveguide probes.
