An instrument and method for analyzing a gas leak. The instrument can obtain a time series of spectra from a scene. The instrument can compare spectra from different times to determine a property of a gas cloud within the scene. The instrument can estimate the column density of the gas cloud at one or more locations within the scene. The instrument can estimate the total quantity of gas in the cloud. The instrument can estimate the amount of gas which has left the field of view of the instrument. The instrument can also estimate the amount of gas in the cloud which has dropped below the sensitivity limit of the instrument.

Gas leak emission quantification with a gas cloud imager

Thermal imaging systems are provided. An example thermal imaging system includes an infrared (IR) imager that acquires IR image data of a field of view of the IR imager. The thermal imaging system further includes video analysis circuitry operably coupled to the IR imager. The video analysis circuitry receives first temperature data of a first field reference within the field of view of the IR imager, receives second temperature data of a second field reference within the field of view of the IR imager, and receives IR image data from the IR imager. The video analysis circuitry calibrates the IR imager based upon the first temperature data, the second temperature data, and the IR image data. The thermal imaging system may further include a temperature control chamber enclosing the IR imager and configured to thermally isolate the IR imager and temperature sensors thermally coupled to the IR imager.

Apparatuses, systems, and methods for thermal imaging

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.

In one embodiment, 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 an optical focal plane array (FPA) unit. 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. Said optical system and said processing unit can be contained together in a data acquisition and processing module configured to be worn or carried by a person.
