SUSI

Abbrev. for Sydney University Stellar Interferometer. An optical interferometer sited at Culgoora, New South Wales, Australia, in operation since 1991. It has 12 small mirrors located along a baseline 640 meters long. The effects of atmospheric turbulence are minimized firstly by using small apertures to gather a relatively clear fraction of the incoming light. In addition, rapid adjustments can be made to small mirrors within each telescope to counterbalance any remaining atmospheric distortion (see adaptive optics).
