    Abstract: Systems, methods, and computer program products for thermal contrast determinations are provided. An example imaging system includes a first infrared (IR) imaging device that generates first IR image data of a field of view of the first IR imaging device and a computing device connected with the first IR imaging device. The computing device receives probe temperature data from a temperature probe indicative of an external environment of the imaging system and receives the first IR image data from the first IR imaging device. The computing device determines background temperature data based upon the first IR image data, determines gas temperature data based upon the probe temperature data, and determines a thermal contrast for each pixel based upon a comparison between the background temperature data and the gas temperature data. The computing device further determines a detection limit for each pixel as a function of thermal contrast.

    Abstract: Methods, apparatuses, and computer program products for fugitive gas quantification are provided. For example, a computer-implemented method may include obtaining gas column density maps associated with one or more gas leak tests, each with an associated distance and leak rate; if the density maps do not meet a predefined quality threshold, filtering the density maps to remove any that do not meet predefined quality metrics and generating a leak rate predictive model based on providing some or all of any remaining density maps that meet the predefined quality metrics, associated distances from the gas leak imaging device to the gas leak tests, and associated leak rates to an artificial intelligence algorithm; and if the density maps meet the predefined quality threshold, generating a leak rate predictive model based on providing some or all of the density maps, associated distances, and associated leak rates to the artificial intelligence algorithm.

    Abstract: An infrared (IR) imaging system for determining a concentration of a target species in an object is disclosed. The imaging system can include an optical system including a focal plane array (FPA) unit behind an optical window. The optical system can have components defining at least two optical channels thereof, said at least two optical channels being spatially and spectrally different from one another. Each of the at least two optical channels can be positioned to transfer IR radiation incident on the optical system towards the optical FPA. The system can include a processing unit containing a processor that can be configured to acquire multispectral optical data representing said target species from the IR radiation received at the optical FPA. One or more of the optical channels may be used in detecting objects on or near the optical window, to avoid false detections of said target species.
