7 December 1993 AXAF optical quality ensurance via the crosscheck process

Properly planned and executed metrology crosschecks at low to mid system test levels can provide up to the same degree of end item performance insurance protection that a top-level end-to-end test can, at a small fraction of the cost, and in a much more timely manner in terms of identifying and correcting problems. This philosophy has been put into rigorous practice on the optics fabrication activity being performed by Hughes Danbury Optical Systems, under contract to TRW, on the Advanced X-ray Astrophysics Facility (AXAF) program being managed by NASA's Marshall Space Flight Center. The process to date, while for the most part having provided confidence that the primary calibrations and tests are correct, has also identified several significant but subtle errors that were corrected. The focus of the paper is on the process itself as an optical quality insurance tool, with examples from AXAF described.
