在本文的第一部分中，我们综述了光学/红外干涉测量在地面天文学中的作用。我们依次讨论了天文干涉测量的起源，其发展的动机，其实现的技术，其天文学意义的例子，以及当前一代干涉测量阵列的局限性。第二部分重点介绍了近10年光学和近红外波段地面天文成像干涉测量技术的发展前景。对决定成像阵列最佳设计的天文和技术因素进行了评估。一项基于科学能力、技术可行性和成本的分析认为，应该由大量中等规模（2米级）的望远镜组成阵列，而不是由少数规模大得多的望远镜组成阵列。
In the first part of this review we survey the role optical/infrared interferometry now plays in ground-based astronomy. We discuss in turn the origins of astronomical interferometry, the motivation for its development, the techniques of its implementation, examples of its astronomical significance, and the limitations of the current generation of interferometric arrays. The second part focuses on the prospects for ground-based astronomical imaging interferometry over the near to mid-term (i.e. 10 years) at optical and near-infrared wavelengths. An assessment is made of the astronomical and technical factors which determine the optimal designs for imaging arrays. An analysis based on scientific capability, technical feasibility and cost argues for an array of large numbers of moderate-sized (2 m class) telescopes rather than one comprising a small number of much larger collectors.
