Abstract
Described herein is a system and method for extending the performance of a simple lens system with curvature of field to image a set of optical light guide sources extended over a wide field of view. Embodiments are applicable to systems using integrated optical light guides as the sources for imaging. Further, the systems and methods allow for a wide field of view using simple aspheric lenses with resulting savings in complexity, size, mass, and cost.
