Abstract
Various embodiments are directed to an imaging system for detecting a greenhouse gas such as sulfur hexafluoride. The system may include a first thermal camera for generating a static image. The first camera may include an uncooled thermal detector and a first spectral filter in an optical path for passing wavelengths within an absorption range of the greenhouse gas. The system may further include a second thermal camera for generating an additional static image. The second camera may include another uncooled thermal detector and a second spectral filter in another optical path for passing wavelengths outside of the absorption range of the greenhouse gas. Both cameras may be aligned with each other and operative to co-collect long exposure images. The system may further include a robotic platform for moving the cameras to facilitate detection of the greenhouse gas based at least in part on a difference between the static images.
