A 3D Multi-Aperture Image Sensor Architecture

An image sensor comprising an array of apertures each with its own local integrated optics and pixel array is presented. A lens focuses the image above the sensor creating overlapping fields of view between apertures. Multiple perspectives of the image in the focal plane facilitate the synthesis of a 3D image at a higher spatial resolution than the aperture count. Depth resolution is shown to continue to improve with pixel scaling below the diffraction limit. Preliminary circuit implementation is described
