Angular Pointing and Guidance for the Sydney University Stellar Interferometer

Autor: W. J. Tango, E. D. Thorvaldson

Publikováno v: Publications of the Astronomical Society of Australia. 13:249-257

The Sydney University Stellar Interferometer (SUSI) uses siderostats (plane, alt–azimuth mounted mirrors) to reflect starlight into the instrument. The analysis of the pointing and guidance of the siderostats by traditional methods is not practical

Aperture area metrology using confocal laser beam scanning technique

Autor: E. D. Thorvaldson, P J Manson, Maitreyee Roy, M. J. Ballico, E G Atkinson

Publikováno v: Scopus-Elsevier

In precision optical radiometric and photometric measurements, one of the limiting factors is an accurate knowledge of the area of a beam limiting aperture. The world's most accurate radiometric measurements are currently realized with a relative sta
