Abstract
The present invention is an analog of a set of human eyes, capturing 3D images on a conjugate pair of foveae, with the additions that (i) there can be multiple, independent, conjugate pairs of foveae, and (ii) under computer control, certain conjugate pairs of foveae can be made to move across the detecting surfaces simultaneously to follow moving objects while the lenses remain fixed. Since foveal fields of view are very narrow—of the order of one degree—and little information is transmitted to the computer (or brain) outside this range—there is almost no cross-talk between foveae. By using multiple foveae within each detector, images may be stitched together by algorithms to produce virtually ghost-free full-field 3D images for display.
