Paper Abstract

Part of the work done under an Air Force contract, and previously under Lockheed's internal funds, has been to find an optical system covering ten's of degrees with arc-seconds resolution. Since we only required a one-dimensional field-of-view, we allowed nonrotational symmetric figuring! Thus we could design an f/2 refractive-corrector-Schmidt-type system that would meet re-quirements. It is a factor of 10 better than a standard Schmidt. The same principle allows a reflective-corrector-Schmidt with better performance than a standard Schmidt. We have analyzed a variety of multiple corrector configurations with outstanding performance, including an f/2 all-reflective system that fully meets requirements, and an f/l. 3 three-refractive-corrector system that exceeds resolution requirements by almost an order of magnitude.
