Methane leakage monitoring system based on light-induced thermoelastic spectroscopy

Abstract

A methane leakage monitoring system based on light-induced thermoelastic spectroscopy (LITES) is proposed in this manuscript. We use our methane leakage monitoring system for methane detection at the wavelength of 1650.961 nm. This system has a minimum detection limit of 62.8 ppm·m and a good linear response (R-square = 0.997). We also simulated methane leakage, and the results show that our system has the ability to monitor methane leakage.
