Patent ID: 8675290

Claim:
An optical imaging system, comprising: a single primary optical facility; a refocusing facility in a primary optical path of the optical imaging system to sample two or more portions of an optical wavefront that pass through the single primary optical facility, and to focus the optical wavefront onto an image plane, the refocusing facility including a plurality of refocusing lenses in a plane; a moving aperture element including at least two apertures positioned to capture two or more different portions of an optical wavefront and movable about a central axis of the single primary optical facility; a splitting facility that splits the one or more portions of the optical wavefront; at least one sensor that receives the two or more different portions of the optical wavefront and provides image data from the optical wavefront as an output; an image processing facility configured to resolve the output from the at least one sensor into a three-dimensional shape of an object; and a feedback facility configured to process image data from the at least one sensor and provide feedback to control a rotation of the moving aperture, wherein the feedback facility controls a rotation of the aperture element to rotationally align the at least two apertures within the optical imaging system according to an expected orientation of an interproximal surface of two adjacent teeth during a dental scan by the imaging system.
