What is Sydney University Stellar Interferometer mean?
The Sydney University Stellar Interferometer (SUSI) was an optical long baseline interferometer owned by The University of Sydney. It was located in the Paul Wild Observatory, 20 km west of Narrabri town in New South Wales, Australia.
The interferometer had several siderostats, which collected and reflected starlight into the optical laboratory for interferometry via two vacuum pipes. Although mirrors at the siderostats were 20 cm in diameter, the effective aperture size was 14 cm as they operated at angles of about 45°. By selecting the different siderostats at different distances, the baseline of the interferometer could be varied between 5m and 640m.
With beam-combining instruments that operated at visible wavelengths (~550-850 nm), SUSI had an angular resolution of up to ~0.7mas (milliarcseconds).
