Paper Abstract

Computer generated holograms (CGHs) are an alternative to refractive or reflective null optics when testing spheric optic components. A key attraction is that the difficulty of designing and fabricating a CGH null is largely independent of the detailed shape of the test asphere. CGH nulls have been used quite successfully in a number of high profile programs, but certification issues have limited their more widespread acceptance as a primary testing means. This is due largely to unfamiliarity with appropriate verification and certification methods. We here discuss specification and tolerancing of CGH nulls and present a comprehensive methodology for verification and certification.
