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.
We present a gigapixel-scale multi-aperture microscope capable of measuring a sample’s 3D height profile over multi-centimeter-scale fields of view with a series of single synchronized camera snapshots. Exploiting the overlap redundancy in our multi-aperture camera array microscope, we developed a novel, end-to-end photogrammetric reconstruction algorithm that simultaneously calibrates the cameras’ 3D positions and poses, stitches the acquired images, and generates a coregistered, pixel-wise 3D height map of the sample. Our work opens the door to video-rate 3D monitoring of dynamic scenes at micrometer-scale resolutions and centimeter-scale fields of view.
