1. An imager array, comprising: a plurality of focal planes, where each focal plane comprises a two dimensional arrangement of pixels having at least two pixels in each dimension and each focal plane is contained within a region of the imager array that does not contain pixels from another focal plane; control circuitry configured to control the capture of image information by the pixels within the focal planes, where the control circuitry is configured so that the capture of image information by the pixels in at least two of the focal planes is separately controllable; sampling circuitry configured to convert pixel outputs into digital pixel data; and output interface circuitry configured to transmit pixel data via an output interface.
