Abstract:
1. An imaging system, comprising: a lens situated to receive a light flux from an object and form a real image of the object; an imaging detector situated so as to receive the real image of the object from the lens, wherein the imaging detector is a detector array that includes a plurality of detector elements; a lens aperture situated to establish a lens f-number; and a spatial light modulator situated proximate the lens so as to receive and transmit the light flux associated with the real image to the detector array and to selectively attenuate at least some portion of the received flux, wherein the spatial light modulator includes a plurality of light modulator elements, and the imaging detector and the spatial light modulator are situated so that one or more of the detector elements correspond to one or more of the light modulator elements, wherein the spatial light modulator is secured to the lens or the imaging detector and the plurality of light modulator elements define a modulator plane that is parallel to a detector plane.
