Abstract

An in-line typed compact Raman lidar system for leaked hydrogen gas detection was developed. In this study, the signal gain was improved to detect low concentration hydrogen gas. The improved lidar could detect Raman scattering light of atmospheric nitrogen up to a range of 50 m. Raman scattering light by hydrogen gas in a gas cell could be detected for concentrations of 13% to 100%.
