| Abstract: | This paper introduced the MAX1978-based temperature control circuit which was used for photoacoustic detection system and controlling and stabalizing DFB laser temperature. 10 K negative temperature coefficient of resistance was used as temperature sensors and TEC temperature as the implementation of the device. The results show that the response time is less than 10 s, the temperature stability of the accuracy is better than 0. 02 ℃. |
