Paper Abstract

A Raman lidar system for detection of hydrogen gas has been developed. The lidar system consists of a pulsed Nd:YAG laser of wavelength 355 nm and a Newtonian telescope of aperture 212 mm. The system can detect hydrogen gas by either rotational or vibrational Raman backscatter up to a distance of 30 m in outdoor, daylight conditions. Furthermore, the system can perform two-dimensional mapping of the hydrogen gas distribution by spatial scanning of the laser beam within the telescope field of view.
