Abstract
An imaging system (10) for imaging an emitting gas (12) includes an imager (16) and a laser source (20). The imager (16) captures an image (18) of light in the mid-infrared (MIR) range. The laser source (20) includes a semiconductor laser (334) that directly emits an output beam (26) that is in the MIR range. The output beam (26) may be adapted to backscatter near and/or be absorbed by the emitting gas (12). Thus, when an emitting gas (12) is present, the gas (12) may absorb and attenuate the backscattered light. As a result thereof, a shadow or contrast (18A) corresponding to the emitting gas (12) may be visible in the image (18) that is captured by the imager (16).
