Abstract
A gas detection system is disclosed that uses an infrared illumination source and an infrared imaging detector. The infrared source is selected to emit at wavelengths corresponding to an absorption band of a gas to be detected. The region to be analyzed for the gas is illuminated, and the infrared radiation reflects off of local surfaces back to the imaging detector. At locations where the gas is present, the infrared radiation is absorbed which reduces the back reflection to the detector.
