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.
