超导探测器将在天体物理学中发挥越来越重要的作用，特别是在毫米到远红外波长，其中的科学机会包括天文学和宇宙学中的关键问题。超导探测器提供了许多好处：出色的灵敏度，光刻制造，和大阵列尺寸，特别是通过最近的多路复用技术的发展。本文介绍了科学的机会，这些设备的基本物理，辐射耦合技术，并回顾了最近的进展，直接探测器，如过渡边缘测辐射热计，隧道结（超导体-绝缘体-超导体）和热电子混频器的工作。
Superconducting detectors will play an increasingly significant role in astrophysics, especially at millimeter through far-IR wavelengths, where the scientific opportunities include key problems in astronomy and cosmology. Superconducting detectors offer many benefits: outstanding sensitivity, lithographic fabrication, and large array sizes, especially through the recent development of multiplexing techniques. This paper describes the scientific opportunities, the basic physics of these devices, the techniques for radiation coupling, and reviews the recent progress in direct detectors, such as transition-edge bolometers, and the work on tunnel junction (superconductor-insulator-superconductor) and hot-electron mixers.
