Patent ID: 8681337

Claim:
A gas filter correlation radiometery (GFCR) system, comprising: a plurality of gas cells, each of said gas cells disposed to receive light energy associated with a common field-of-view of an atmospheric region, each of said gas cells having contents selected from the group consisting of a vacuum and a gas of unique composition wherein, for each of said gas cells, the light energy passed therethrough is spectrally affected by said contents thereof and then output therefrom as a spectrally-affected beam of light energy associated with said common field-of-view; an optical detector; an optical system disposed between said gas cells and said optical detector for imaging each said spectrally-affected beam on a unique region of said optical detector; an image processor coupled to said optical detector for generating matched portions of each said spectrally-affected beam so-imaged on said optical detector wherein each of said matched portions corresponds to an identical portion of said common field-of-view; and a GFCR processor coupled to said image processor for performing GFCR computations using said matched portions.
