Nonrotationally Symmetric Corrections for Optical Systems with Nonrotationally Symmetric Filed-of-View Requirements.
Abstract
The patent application discloses the novel structure of six preferred embodiments of variations of the Schmidt-type telescope, wherein the telescope has a one-dimensional field-of-view requirement. The variations include: a conventional refractive corrector Schmidt system; an all reflective Schmidt system; a Baker three corrector variant of a Schmidt refractive corrector system; a three mirror concentric system; a centered corner corrector reflective Schmidt system; and, a triple reflective corrector system. The variations provide a factor of about 10 improvement in spot size over the standard Schmidt. In addition, elliptical aperture shaping is taught which, in certain cases, provides a factor of 2 improvement over a circular aperture.
