Abstract
A variable field of view optical system and method comprising providing a forward curved optical element, providing a rearward optical element comprising an axially gradient index material, providing a curved focal surface, and conveying an image on the curved focal surface to a flat detector surface.
Claims25
A variable field of view optical system comprising:
- a forward curved optical element;
- a rearward optical element comprising an axially gradient index material;
- a curved focal surface;
- and
- means for conveying an image on said curved focal surface to a flat detector surface, wherein said means comprises a plurality of optical fibers, and wherein said fibers are concentrated more densely in a center of said focal surface than in a periphery of said focal surface.
