光子成像技术应用于量子信息通信、生物成像等多个研究领域。我们一直在开发光子计数装置使用光学跃迁边缘传感器（TES）。我们展示了一个单光子光谱成像系统，包括一个光学TES和扫描显微镜。然而，需要大量的TES像素来增加成像系统中的视场。为了读出TES阵列，需要对输出信号进行复用。微波SQUID复用器（MW-Mux）是一种频率复用方法，其载波具有几GHz的频率，并且它可以用于加宽频带。在本文中，我们报告的第一个演示读出的光学TES与MW-Mux。
Photon imaging technology is applied in various research fields such as quantum information communication and biological imaging. We have been developing photon-counting devices using optical transition edge sensors (TES). We demonstrated a single-photon spectroscopic imaging system comprising an optical TES and a scanning microscope. However, a great number of TES pixels are required to increase the field of view in the imaging system. To read out the TES array, output signals need to be multiplexed. Microwave SQUID multiplexer (MW-Mux) is a kind of frequency multiplexing method with a carrier wave having a frequency of several GHz, and it can be used to widen the frequency band. In this paper, we report the first demonstration on readout of an optical TES with MW-Mux.
