过渡边缘传感器（TES）表现出高能量分辨率的单个光子已被应用于光子计数显微镜的生物成像。本文讨论了具有大有效面积的TES阵列的发展，以扩大光子计数显微镜的视场，并制作了一个光学TES阵列，包括一个Ti/Au双层在Si衬底上。热干扰，由于焦耳功率不影响的时间常数和能量分辨率的探测器在TES阵列中，即使在探测器的焦耳功率改变了23%。相邻探测器之间的光子信号串扰为-40 dB，可以忽略不计。通过Si衬底的热传导在相邻探测器之间的光子信号串扰中占主导地位。
Transition-edge sensors (TESs) exhibiting high energy resolution for single optical photons have been applied to photon-counting microscopy for biological imaging. This paper discusses the development of TES arrays with large effective areas to expand the field of view of photon-counting microscopy and has fabricated an optical TES array comprising a Ti/Au bilayer on a Si substrate. Thermal interference due to Joule power did not affect the time constant and energy resolution of a detector in the TES array, even though the Joule power in the detector was changed by 23%. The photon signal crosstalk between adjacent detectors was - 40 dB which was negligible. Heat conduction through the Si substrate was dominant in the photon signal crosstalk between adjacent detectors.
