Abstract: An optical system that produces a digital image of a field of view, comprising: a) a sensor array of light sensors that produces an output signal indicating an intensity of light received by each light sensor; b) one or more optical elements that together project an image of the field of view onto the sensor array, including at least one sectioned optical element comprising a plurality of sections, at least two of the sections differing in one or both of size and shape, each section projecting onto the sensor array an image of only a portion of the field of view, the different sections projecting images of different portions of the field of view to non-overlapping regions of the sensor array.

Abstract: An image processing guide comprising: a solid body comprising: a plurality of surfaces defining an optical pathway from an input surface to an output surface, where the optical pathway connects the plurality of surfaces successively; wherein the plurality of surfaces comprises at least one curved reflective surface configured to receive light from the optical pathway and to return light to the optical pathway; wherein the optical signal is not focused to an image plane within the solid body.
