Title: Dual-CGH Interferometry Test for X-Ray Mirror Mandrels
Published: June 15, 2008
Abstract: We describe a glancing-incidence interferometric double-pass test, based on a pair of computer generated holograms (CGHs), for mandrels used to fabricate x-ray mirrors for space-based x-ray telescopes. The design of the test and its realization are described. The application illustrates the advantage of dual-CGH tests for the complete metrology of precise optical surfaces.
