A system and method for wide angle imaging create a high resolution image using a convex primary mirror concentrically positioned relative to a concave secondary mirror and one or more detectors spherically juxtaposed. The radii of the primary and secondary mirrors are related by the square of the "golden ratio" to reduce low order aberrations. A fiber optic faceplate coupled to each detector corrects field curvature of the image which may then be detected with a conventional flat detector, such as a CCD camera.

[ What is claimed is:] [1.] A system for imaging a wide angle field of view, the system comprising:an annular spheroid having a convex surface for reflecting incident energy radiating from the field of view, the annular spheroid having an axially extending aperture, an associated center point, and a first radius extending from the center point to the convex surface;a second spheroid having a concave surface for reflecting energy propagating from the annular spheroid toward the center point, the second spheroid positioned concentrically relative to the annular spheroid and having a second radius extending from the center point to the concave surface; andat least one detector positioned to receive at least a portion of the energy reflected from the second spheroid, the detector including a fiber optic faceplate having a plurality of fibers with first and second ends and varying lengths, the plurality arranged such that the first ends are substantially coplanar and the second ends define a generally convex spheroidal surface.
