Wide-Angle Camera Using Achromatic Doublet Prism Array And Method of Manufacturing The Same

摘要

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.

1. A method for manufacturing an achromatic doublet prism array having a N×M number of sections, the method comprising:
forming an array of first prisms each located in one of the N×M sections, composed of a first material, onto a substrate; and, forming an array of second prisms each located in one of the N×M sections, composed of a second material different than the first material, atop the array of first prisms.
