超导探测器阵列已成为当前单个（单碟）望远镜上毫米波和亚毫米波天文仪器的标准技术。超导外差阵列用于光谱测量，直接探测器阵列用于光度成像和低分辨率光谱。这些直接探测器阵列中的大多数由具有超导温度计的测辐射热计组成，称为过渡边缘传感器（TES），并且用多路复用超导量子干涉器件（SQUID）电流放大器读出。另一种称为动态电感探测器（KIDS）的超导探测器技术也开始用于新的天文仪器。本文介绍了这两种类型的探测器的性能和未来发展的前景，这两种类型的技术向更大的像素计数和更有能力的仪器。
Superconducting detector arrays have become the standard technology for the current generation of millimeter-wave and submm-wave astronomical instruments on individual (single dish) telescopes. Superconducting heterodyne arrays are used for spectroscopic surveys and direct detector arrays are used for photometric imaging and low resolution spectroscopy. Most of these direct detector arrays consist of bolometers with superconducting thermometers called Transition Edge Sensors (TES) and are read out with multiplexed superconducting quantum interference device (SQUID) current amplifiers. Another superconducting detector technology called Kinetic Inductance Detectors (KIDs) is starting to be used in new astronomical instruments as well. This review describes the properties of these two types of detectors and the prospects for future development of both types of technologies toward larger pixel counts and more capable instruments.
