Patent ID: 6856466

Claim:
An apparatus, for producing a plurality of images of a single object scene, comprising: a first telecentric optical sub-system, without inclusion of a filter, said first telecentric optical sub-system including at least one refractive optical element and being capable of focusing incoming radiation from the single object scene onto a focal plane; a field stop located at a plane substantially coincident with the focal plane of the first telecentric optical sub-system; a second telecentric optical sub-system capable of substantially collimating radiation received from the field stop, the field stop being positioned between the first telecentric optical sub-system and the second telecentric optical sub-system; a beam separating sub-system capable of separating into a plurality of substantially collimated beams of radiation the substantially collimated radiation received from the second telecentric optical sub-system; a third optical sub-system capable of forming the plurality of images on an imaging plane from said plurality of substantially collimated beams of radiation received from the beam separating sub-system, the beam separating sub-system being positioned between the second telecentric optical sub-system and the third optical sub-system, the third optical sub-system being positioned between the beam separating sub-system and the imaging plane.
