Holographic Alignment Breadboard
Abstract
Previous studies have shown the utility of a nonlinear grating on the primary mirror of a laser beam pointing system. The nonlinear grating can focus a full aperture sample of the laser beam or an alignment beam to a conveniently located alignment sensor, where it is used for wavefront error diagnostic and control purposes. The Holographic Alignment Breadboard (HOLAB) program designed, fabricated, and tested the holographic grating laser beam sampler alignment technique just described. A breadboard system was built which incorporated an ox-axis primary mirror with a 30 centimeter diameter and an F-number of F/1.5. Tests were conducted with the breadboard to establish the operational properties of this technique. The experimental data correlated well with analytical predictions.
