Glossary:Laser leak detection
Methods for locating potential methane emissions sources by using laser frequencies that are tuned to be absorbed or scattered by a target gas species.
(Note - This technology allows operators to safely scan a facility and equipment from a distance provided the background provides appropriate reflective return of the laser signal. It also prevents operators from walking the entire length of a pipeline or service line, allowing them to stay in place and scan for leaks along the sight line)[1]
