Methane Leak Detection Using Chirped Laser Dispersion Spectroscopy

Not Accessible

Your library or personal account may give you access

Abstract

We present a real-time chirped laser dispersion spectrometer capable of distinguishing path-averaged methane leaks 0 to 8 ppm above the ~2ppm background methane level using low reflectivity (down to 0.01%) surfaces 50 m away.
