Abstract
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.
Claims10
An infrared (IR) imaging system for quantifying one or more parameters of a gas cloud, the IR imaging system comprising:
- an optical system comprising an optical focal plane array (FPA) unit, the optical system having components defining at least two optical channels thereof, the at least two optical channels being spatially and spectrally different from one another, each of the at least two optical channels positioned to transfer IR radiation incident on the optical system towards the optical FPA unit;
- and
- a data-processing unit comprising one or more processors, the data-processing unit configured to:
- acquire spectral optical data from IR radiation received at the optical FPA unit, and
- determine an estimate of loss caused by a portion of the gas cloud being blown out of a field of view of the optical system.
