We present a novel approach, based on the use of an array of cameras with custom optics, which can capture snapshot stereoscopic gigapixel images across 1cm2 area at 1-micrometer half-pitch resolution. Our system uses a large space-bandwidth product objective lens to form an intermediate image, which is captured by 96 micro-cameras arranged in a flat array. Each camera records a 10-megapixel image from a unique section of the sample, which are then stitched to produce the final composite. Our system is well suited for applications in digital pathology and in vitro cell-cultures imaging.
