Abstract
A wide-angle camera and fabrication method thereof includes a sensor with a plurality of pixel sub-arrays and an array of optical elements on a first side of a substrate. Each of the optical elements is capable of forming an image from a field of view onto a different one of the pixel sub-arrays. The wide-angle camera also includes an array of achromatic doublet prisms on a second side of the substrate, where each of the achromatic doublet prisms is aligned to provide a viewing angle with a different one of the optical elements. The sensor captures a wide-angle field of view while having a compact format.
