摘　　要：单光子探测技术作为推动前沿科技发展的重要支撑技术之一,在核物理学中微子观测、绿色荧光蛋白检测、用于生物成像的超高分辨率显微镜以及量子信息通信等领域中均发挥着重要作用。因此,更高性能单光子探测器的研制一直受到极大关注。与传统单光子探测器相比,超导转变边沿单光子探测器在量子效率、暗计数、能量分辨和光子数分辨等方面提供了更加卓越的性能。本文从超导转变边沿单光子探测器的工作原理、性能测试系统、主要性能及研究进展等方面进行了简要综述,对该探测器未来的研究具有重要的参考意义。As one of the important supporting technologies to promote the development of cutting-edge science and technology, single-photon measurement plays an important role in observing neutrinos in nuclear physics, detecting photons from green fluorescent protein, super-resolution microscopes for bioimaging, and quantum information communication. Therefore, the development of higher-performance single-photon detectors has been receiving great attention. Compared with traditional single-photon detectors, superconducting transition-edge based single-photon detectors provide superior performance in terms of quantum efficiency, dark count rate, energy resolution, and photon number resolving capability. In this paper we review the operating principle, measurement system, main performance and research progress of super-conducting transition-edge based single-photon detectors, which has important reference significance for the future research.
