Tunable diode laser absorption spectroscopy technique is qualitative or quantitative gas analysis technology which is obtained from the characteristics of absorption lines based on gas absorption spectra using diode laser wavelength tuning characteristics. Also a set of long distance on-line gas monitoring system of acetylene (C_2H_2) is designed to make use of harmonic detection technique with the multiple reflection pool on the extraction of weak signal processing. Through the experiment it is possible to monitor the concentration of acetylene quickly and accurately.
