摘要
非制冷热象仪中焦平面的温度决定了红外探测器的成像质量,保证UFPA温度稳定是红外成像质量的关键技术之一。设计可调整PID补偿网络参数的温度控制电路,可提高温度控制的稳定性。实验验证了:整个温度控制电路精度高、稳定性好并可以根据实际应用调整参数,对非制冷红外焦平面温度控制的应用具有参考价值。
In the uncooled infrared camera, imaging quality of the uncooled infrared detector is determined by the temperature of UFPA, so the UFPA＇s temperature stability is a key technology to the infrared imaging quality. A temperature control circuit with PID compensation network of adjustable parameter is designed to improve the temperature control stability,and its efficiency is proved by a large number of experiments. The given tempera- ture control circuit features high precision and stability, and can adjust the parameter according to practical application, being a reference to the temperature control of UFPA.
