众所周知,以光辐射、光电导性或光生伏打等效应为基础而制成的一类检测器称作量子检测器,而这里要介绍另一种重要的光电检测器——热测器的功能。热测器通过一个较间接的过程感受光。当物质吸收了光能以后,温度上升,通过温度的变化来感受光,就好比我们从太阳光中感受到温暖一样。 It is well-known that a class of detectors based on the effects of photoradiation, photoconductivity or photovoltaics are called quantum detectors and here is another important photodetector, the function of a thermal detector . The thermal sensor senses light through a more indirect process. When the substance absorbs light, the temperature rises and the light changes by the temperature, just like we feel the warmth from the sunlight.
