摘要

Our novel automated feedback temperature controlled cooling system consists of a temperature measurement circuit, a TE cooler, a thermistor, a microcontroller, and a digital-to-analog converter and PWM algorithms. The measurement accuracy of this temperature controlled TE system was better than 0.1° C and can be used for maintaining an instrument's isothermal applications. The experimental results of SWIR linear image shows that the temperature can be stably maintained at -20° C, the dark output current can be reduced almost 80mV (Integration time: 100 ms) and the SNR of pixel can be improved from 48 dB to 83 dB as well.
