一种红外焦平面温度监测电路

摘要

制冷型红外探测器的工作温度严重影响着其性能,在工作过程中,必须对其工作温度进行监测.法国sofradir公司的红外探测器组件采用晶体管2N2222的发射结作为其温度监测的传感器.设计了一种红外焦平面探测器的温度实时监测电路,并采用替代电阻对温度进行标定.%Working temperature of cooled infrared detectors seriously affects their performance. In the course of their work, their working temperature must be monitored. France sofradir' s infrared detector components use emitter of transistor 2N2222 as their temperature sensors. A real-time infrared focal plane detector temperature monitoring circuit is presented, and a temperature calibration method is used alternative resistance.
