悉尼大学恒星干涉仪（SUSI）是一种新的长基线光学干涉仪，位于澳大利亚新南威尔士州北方。SUSI是为了解决恒星天体物理学中的一系列问题而开发的，它的设计是基于一个成功的原型仪器。在其初始配置中，使用从覆盖5至640米范围的固定南北基线阵列中选择的单一基线进行观测。采用小孔径、波前倾斜校正和快速信号采样技术克服大气湍流的影响，并通过动态光延迟线保持光路的均匀性。介绍了计划中的天体物理方案、由此产生的设计标准、仪器及其现状。
ABSTRA C T The Sydney University Stellar Interferometer (SUSI) is a new long-baseline optical interferometer located in northern New South Wales, Australia. SUSI has been developed to tackle a range of problems in stellar astrophysics, and its design is based on a successful prototype instrument. In its initial configuration, observations are made with a single baseline selected from an array of fixed north‐south baselines covering the range from 5 to 640 m. Small apertures, wavefront-tilt correction and rapid signal sampling are employed to overcome the effects of atmospheric turbulence, and optical path equality is maintained by a dynamic optical delay line. The planned astrophysical programmes, the resulting design criteria, the instrument and its current status are described.
