GAS LEAK DETECTOR AND DETECTION METHODS

A gas leak detector includes a solar detector and a signal filter. The solar detector generates an electrical response by interfering a light signal with a solar signal and detecting a resultant interference signal. The signal filter is communicatively coupled to the solar detector and filters the e...

Beschreibung
Zusammenfassung:	A gas leak detector includes a solar detector and a signal filter. The solar detector generates an electrical response by interfering a light signal with a solar signal and detecting a resultant interference signal. The signal filter is communicatively coupled to the solar detector and filters the electrical response to isolate a beat-note signal. The beat-note signal has an amplitude that is inversely related to a concentration of a species that forms a gaseous plume located along a path of the solar signal.
