摘要

In order to improve and expand the field of X-ray astronomy, and imaging in general, we find that these days a comprehensive systems engineering approach to X-ray image formation must be undertaken. While some industrial interests have taken steps in this direction, any academic approach is lacking from within the archival literature to date, and there are virtually no established university courses. Indeed, it would seem that top level, optical-systems-engineering is exclusively reserved for those seasoned professionals who have accumulated (though somewhat artistically) the “know-how” to efficiently conceive and implement excellent optical designs. Such expert knowledge is not and should not be mysterious.; To this end, we attempt to formulate a highly comprehensive approach to X-ray optical systems engineering and implement it within the context of the Wolter Type-I and Type-II (grazing incidence) telescopes currently utilized for practical X-ray/EUV astronomy. In addition, we will transform the classical paraboloid-hyperboloid designs into ‘aplanatic’ and ‘isoplanatic’, hyperboloid-hyperboloid systems, where certain coma conditions are minimized. As will be shown, one gains little improvement in performance when choosing a quasi-aplanatic mirror design over a classical one, owing to scatter and other image degradation effects. Next we will show that a generalized hyperboloid-hyperboloid design can be comprehensively optimized for any imaging requirement, where the operational field-of-view is weighted according to spatial information content. Our H-H design has been optimized for the GOES Solar X-ray Imager mission and adopted by NASA and NOAA. It is currently undergoing fabrication by Raytheon Optical Systems Inc. who is under subcontract to the Lockheed-Martin Solar and Astrophysics Laboratory. Our design is expected to result in an 80% increase in optical system performance over the original SXI baseline design.
