Abstract
An f-theta lens system for a camera that provides a wide field-of-view, relatively low distortion, and a compact footprint. The lens system comprises four molded plastic elements with seven aspheric surfaces. Within a total thickness of 2.5 millimeters, the system is able to provide an image that is 1.2 millimeters across with a horizontal field of view of 127 degrees. The images produced by the system are well-suited for use with conventional face tracking algorithms designed to process rectilinear images produced by cameras with a narrower field of view.
