普朗克公式与光子探测器温度季向琦（北京装甲兵工程学院）本文从普朗克公式出发，讨论了在可见光和红外波段情况下的光子探测器的温度问题。由一系列分析可知，光子探测器在可见光波段上不需要低温制冷，在红外波段上则必须低温制冷，只有这样，才能有效地降低噪声电平，... Planck’s Formula and Photon Detector Temperature QIU Qi (Beijing Academy of Armored Force Engineering) Based on the Planck’s formula, this paper discusses the temperature problem of photon detectors in the visible and infrared bands. From a series of analyzes we can see that photon detectors do not need cryogenic refrigeration in the visible wavelength range and cryogenic refrigeration in the infrared range, so as to effectively reduce the noise level, ...
