Abstract:
A system for the detection and localization of gas emitted from a container, the system comprising:a light source for producing non-pulsing light;means for scanning said non-pulsing light across a surface of the container;a light source for producing visible light colinear with the non-pulsing light for visualizing the non-pulsing light;a photoactive tracer gas pressurized within said container;means for detecting photoacoustic sound; andmeans for processing said photoacoustic sound, said means for processing said photoacoustic sound being non-synchronous with said means for scanning said non-pulsing light, wherein said non-pulsing light excites said gas leaking from said container creating a photacoustic sound with said means for detecting the photoacoustic sound, and said means for processing said photoacoustic sound non-synchronously with said means for scanning said non-pulsing light.
