    Abstract
  • A methane sensor system was designed based on tunable diode laser absorption spectroscopy (TDLAS) technology and the feature of vertical cavity surface emitting laser (VCSEL) with wavelengths up to several nanometers. We studied the gas present in the methane sensor's common operation environment. Through absorption spectrum stimulation and experiments,we analyzed the cross interference of the gas of H 2O, CO and CO 2to methane detection. The results prove that this laser methane sensor has the characteristics of high stability and anti-cross interference.
