An interferometric fringe scanner was used for the Technology Mirror Assembly (TMA) x-ray telescope, built by Perkin-Elmer as a technology demonstration for the Advanced X-Ray Astrophysics Facility (AXAF). We discuss advanced data processing features

This paper describes the design and summarizes the performance of the recently completed SOAR telescope Active Optical System (AOS). This system is unique in that it uses a thin, solid 4.3-meter diameter ULE lightweight meniscus primary mirror only 1

The Advanced X-ray Astrophysics Facility (AXAF) contains nested sets of Wolter Type 1 x-ray telescopes. The high resolution optical performance required, coupled with the size of the mirrors, necessitates enormous quantities of data to characterize t

A phase retrieval algorithm, developed and implemented by Perkin-Elmer, is used as a technique for in-orbit alignment of the optical system in NASA's Space Telescope. Reasonably accurate estimates of wavefront aberrations are obtained from measuremen

The characterization of the surface of a cylindrical optic requires metrology techniques that are analogous to those for more conventional optics but much different in format. Data on the surface figure can be obtained using interferometry and a frin
