A gas imaging system comprises a lenslet array configured to receive thermal radiation from a scene and transmit a plurality of substantially identical sub-images of the thermal radiation; a birefringent polarization interferometer configured to generate an optical path difference for each ray of the plurality of sub-images based on a respective position of each ray entering the BPI, the optical path differences combining to form an interference fringe pattern; and an infrared focal plane array configured to capture a thermal image of the plurality of sub-images modulated by the interference fringe pattern due to the optical path differences through the BPI. The captured thermal image may represent a plurality of interferogram sample points of the thermal radiation from the scene, and may be used to construct a plurality of hyperspectral images of the thermal radiation from the scene.
