Paper Abstract

High accuracy optical alignment generally requires interferometric methods. A simple computer aided interferometric optical alignment procedure, for the visible, IR and other regions, utilizing the Interferogram Interface in CODE V, is described. The accuracy of visual interferometric alignment is limited and involves highly skilled personnel. To overcome these limitations, a procedure is presented that requires specification of the nominal optical system design, the alignment parameters, such as tilts and decenters in CODE V, and entering in to the latter the interferometrically measured system wavefront data of several different points in the field of view. The last step consists of predicting the alignment parameters such that the system wavefront error is reduced. This procedure is repeated until the wavefront error falls within system specifications. A numerical alignment simulation and an actual system alignment are presented for an F/10, 8 inch diameter Cassegrain objective.
