ABSTRACT:
A system for remote quantitative detection of fluid leaks from a natural gas or oil pipeline by use of an airborne platform; including at least one laser light source for nearly simultaneous illuminating two or more target fluids and a background, wherein the two or more target fluids are characterized by two or more absorption wavelengths, and wherein the background has a different wavelength than either of the two or more target fluids. The illumination source is pointed based on a positioning system while in a geometric area along a path two or more target fluids are scanned for using the illumination sources. A signal detector detects the two or more target fluids using quantitative signal processing. Also included are a controller, a path planning and path finding tool for the positioning of the airborne platform, and a communicator for communicating the presence of the detected leak.
