摘要
本文介绍一基于TDLAS技术的便携式CO和CO2遥测仪的设计。对该遥测仪的工作原理,系统设计与嵌入式软硬件实现作了较详细的分析。利用地面等作反射物获取数据,以及波谱调频二次谐波检测技术达到高速高精度的检测。
A portable remote CO and CO2 sensor based on TDLAS technology is introduced. It is designed as a man-portable absorption telemeter using a topographical target.The designing and developing methods has been well analyzed in detail. High speed and sensitivity is accomplished by means of second-harmonic detection using frequency-modulation spectroscopy.
