Abstract
A multi-point gas sensor network based on a frequency-modulated continuous wave technique and wavelength modulation spectroscopy has been demonstrated for the detection of acetylene gas. A minimum detectable concentration of 6.75ppmrn is obtained with a three-sensor system. The crosstalk between the sensors is estimated about -22 dB.
