常温条件下的非接触式测温、红外光导摄象管、侵入警报器、火灾报警器和激光探测器等,都要求有良好的性能。因被探测目标辐射的光位于红外波段,故需要良好的红外探测元件。红外探测元件大体上分为量子型和热型两种。量子型红外探测元件是利用红外辐射的光子引起探测元件材料中的电子状态变化,使材料的电学性质改变。热型红外探测元件是利用红外辐射的光子能量,使探测元件材料的温度产生变化,引起物理机械性能的改变。前者灵
Non-contact temperature measurement at room temperature, infrared light guide tube, intrusion alarms, fire alarms and laser detectors, etc., require good performance. Since the light radiated by the target to be detected is located in the infrared band, a good infrared detecting element is required. Infrared detection components are roughly divided into two kinds of quantum and thermal type. Quantum infrared detection element is the use of infrared radiation photons cause the detection of electronic components in the material state changes, the electrical properties of the material change. Thermal infrared detection element is the use of photons of infrared radiation energy, the detection element material temperature changes, causing changes in physical and mechanical properties. The former spirit
