Abstract:
A gas concentration-length quantification method may include: acquiring a multi-spectral image of detected radiance including a plurality of pixels using a multi-spectral optical gas imaging camera; estimating a background radiance for at least one of the pixels; calculating a gas concentration-length for the at least one of the pixels based on the detected radiance and the estimated background radiance; and triggering an alert when each alert condition in a list of alert conditions is satisfied. A multi-spectral configuration of the camera may include a reference band that is outside an absorption window of a target gas and an active band that includes at least a portion of the absorption window. Estimating the background radiance may include determining a model relating a detected radiance of the active band to a detected radiance of the reference band and using the model to estimate the background radiance for the active band.

Claim (Index 4):
The method according to  claim 1 ,\n wherein the multi-spectral configuration includes a plurality of active bands, wherein the active bands and the reference band are determined using a plurality of longpass filters equal in number to the number of active bands plus one, wherein each of the active bands includes the reference band, and wherein the plurality of active bands comprises a first active band, wherein the first active band is a first difference between a first longpass filter and a reference longpass filter of the plurality of longpass filters.
