Abstract

An optical device has been developed that passively compensates for certain instrumental angular and/or translationalbeam misalignment errors internal to a laser beam projector. This device insures that centroid of the projected beam remains centered with the optic axis of the projection optics in spite of these errors. Several concepts for such a compensator are mentioned, and the performance of one concept that has been reduced to functional hardware form is summarized. The intended application of this device in an alignment subsystem that senses relative translational errors of separated components in an optical instrument is briefly described.
