Abstract
A gas detector () for remote gas detection in a target region () comprises a light source () for emitting a light beam () into the target region and a light sensor () for sensing light returning therefrom. The light beam is wavelength-modulated around an absorption wavelength of the gas. A controller () is operatively connected to the light sensor for detecting a presence of the gas on a path of the light beam based on returning light sensed by the light sensor. An indicator () that is operatively connected to the controller indicates the presence of the gas. A scanning device () is arranged with respect to the light source so as to scan the light beam through the target region, and with respect to the light sensor so that the light sensor receives the returning light via the scanning device. The indicator cooperates with the scanning device to indicate a position of the gas in the target region.
