Abstract
An imaging system with an integrated source and detector array. A plurality of light detectors are arranged in a detector array and a plurality of light sources corresponding to detectors in the detector array are arranged in a source array in an epi-illumination system so that light radiated from a point on the object illuminated by a given source is detected by a corresponding detector. An optical system is disposed with respect to the source array and the detector array so as to illuminate an object with light from the source array and image the object on the detector array. Ordinarily, the sources and detectors are coplanar and, preferably, are fabricated or at least mounted on the same substrate. One or more sources in the source array may have a corresponding plurality of detectors, and one or more detectors in the detector array may have a corresponding plurality of sources. In one embodiment the Airy pattern of the point response of the optical system encompasses both a detector and its corresponding light sources. In another embodiment, the optical pathway is split by a diffractive element to produce conjugate points corresponding to light sources and their respective dete…
