Abstract

A dual band hyperspectral framing aerial reconnaissance camera includes an objective optical subassembly for receiving incident radiation from a scene external of the vehicle, and a dividing element receiving radiation from the objective optical subassembly. The dividing element directs radiation into a first optical path for imaging in a first band of the spectrum and a separate second optical path for imaging in a second band. A first two-dimensional electro-optical detector in the first path generates a first series of images and a second two-dimensional electro-optical detector in the second optical path generates a second set of imagery. At least one of the first and second electro-optical detectors comprises a hyperspectral imager.
