Measuring coalignment of retroreflectors with large lateral incoming-outgoing beam offset

Schutze, D; Farrant, David; Shaddock, Daniel; Sheard, Benjamin; Heinzel, G; Danzmann, Karsten


A method based on phase-shifting Fizeau interferometry is presented with which retroreflectors with large incoming-outgoing beam separations can be tested. The method relies on a flat Reference Bar that is used to align two auxiliary mirrors parallel to each other to extend the aperture of the interferometer. The method is applied to measure the beam coalignment of a prototype Triple Mirror Assembly of the GRACE Follow-On Laser Ranging Interferometer, a future satellite-to-satellite tracking...[Show more]
