Abstract

We report remote detection of oil using a flash Raman lidar system. The utilization of an expanding laser beam and an intensified CCD camera enabled the wide field-of-view observation, capturing the whole scene simultaneously. The second harmonic of a standard Q-switched Nd:YAG laser (532 nm) provided the illumination of the water and oil samples separately prepared under atmospheric conditions. We demonstrated the possibility of remote flash Raman lidar measurements using the interference filters at the water (649 nm) and oil (623 nm) Raman wavelengths.
