Glossary:Infrared camera
Optical device (camera) equipped with infrared sensors for detecting gases that have infrared absorption bands within the band-pass filter installed in the device. Includes Optical Gas Imaging (OGI) and forward-looking IR cameras.
(Note - Hydrocarbon emissions absorb infrared (IR) light at a certain wavelength and an IR camera uses this characteristic to detect the presence of hydrocarbon gas emissions from equipment at an oil and gas facility. The IR camera operator scans the leak area in real time (user selectable for cold/hot temperature environments). This scanned area is viewed as a live, image such that the gas plumes are visible on the camera display due to their absorption of the IR light. IR camera is also an optical gas imaging (OGI) technology.)[1]
Infrared (IR) thermal imaging cameras is a type of IR cameras, and are commonplace in the oil and gas industry. For years, companies have used them for several tasks such examining pipe integrity within process equipment. Recently, though, a highly specialized version of these cameras has made its way into the marketplace for a new application—the monitoring of volatile organic compounds (VOCs), such as methane, being vented into the atmosphere. Forward-looking infrared (FLIR) cameras are one common type of IR thermal imaging camera in use.[2] [3]
