Laser based Hyperspectral Imaging for Stand-off Gas Detection

Not Accessible

Your library or personal account may give you access

Abstract

Mid-infrared imaging and tunable laser spectroscopy were combined to obtain a hyperspectral gas camera for detecting methane leaks. With the setup a detection limit of better than 10 ppm-m and a leakage flow rate of less than 0.5 ml/min methane has been achieved.
