| Abstract: | The temperature stability of the cooled infrared sensor plays an important role in infrared system. In this paper a high precision temperature control system for cooled infrared sensor was designed, which is realized using closed-loop PID by MCU. The temperature is controlled in the range 77～88 K, and the temperature stability is within ±0.05 K. The system also has characteristic of high precision, low noise, fast stabilizing, etc. The experimental results show that the system can work easily and reliably, and attain to the demand of high performance system. |
