1. An infrared (IR) imaging system for imaging a scene, the imaging system comprising:

  • an optical system comprising an optical focal plane array (FPA) unit including a plurality of spatially and spectrally different optical channels to transfer IR radiation from the scene towards the optical FPA unit, each optical channel positioned to transfer a portion of the IR radiation incident on the optical system from the scene towards the optical FPA unit,wherein at least one of the plurality of optical channels is in the mid-wavelength infrared spectral range and at least another one of the plurality of optical channels is in the long-wavelength infrared spectral range,wherein the imaging system is configured to acquire a first video image of the scene in the mid-wavelength infrared spectral range and a second video image of the scene in the long-wavelength infrared spectral range.
