Abstract:
A sensor apparatus comprising:a single superachromatic objective lens for focusing on a focal plane radiation in a subspectrum of the visible/NIR/SWIR reflective spectral region and in a subspectrum of the thermal IR 3-15 micron emissive spectral region from a scene; a beam splitter for receiving radiation from said objective lens and dividing the received radiation into first and second components; a first focal plane array receiving said first component of said radiation and sensing in a subspectrum of the visible/NIR/SWIR spectral region to produce a corresponding first output signal; a second focal plane array receiving said second component of said radiation and sensing in a subspectrum of the thermal IR 3-15 micron spectral region to produce a second output signal; and a composite signal output derived from the signal outputs of said first and second focal plane arrays.
