Simultaneous Detection of CO<sub>2</sub> and CH<sub>4</sub> Using a DFB Diode Laser-Based Absorption Spectrometer

Simultaneous Detection of CO<sub>2</sub> and CH<sub>4</sub> Using a DFB Diode Laser-Based Absorption Spectrometer

In this paper, an attractive gas sensing technique based on fiber optical sensing ideal was developed for the detection of multi-gas species simultaneously. Calibration-free laser absorption spectroscopy (LAS) was used and combined with a multi-pass optical absorption cell, two fiber-coupled near-in...
