Abstract
Improved techniques for thermal imaging and gas detection are provided. In one example, a system includes a first set of filters configured to pass first filtered infrared radiation comprising a first range of thermal wavelengths associated with a background portion of a scene. The system also includes a second set of filters configured to pass second filtered infrared radiation comprising a second range of thermal wavelengths associated with a gas present in the scene. The first and second ranges are independent of each other. The system also includes a sensor array comprising adjacent infrared sensors configured to separately receive the first and second filtered infrared radiation to capture first and second thermal images respectively corresponding to the background portion and the gas. Additional systems and methods are also provided.
