“…It is effective to use a Raman lidar, as a non-contact measurement technique of hydrogen gas concentration distribution [1] [2] . Hydrogen gas measurement by the Raman lidar doesn't have to install a sensor and a syringe into the gas flow, concentration distribution of hydrogen gas can be measured without interference to the gas flow at a measurement point.…”

When change of hydrogen(H2) gas concentration in a certain point is measured, non-contact measurement technology with high temporal and spatial resolution is necessary. In this study, H2 concentration in the small area of <1cm2 under the gas flow was measured by using a Raman lidar. Raman scattering light at the measurement point of 750mm ahead was detected by the Raman lidar. As a result, it was proved that the H2 concentration of more than 100ppm could be successfully measured.
