Paper Abstract

Utah State University has developed a technique to automatically align the optical surfaces in cryogenic interferometers. Although the technique depends on microprocessor sensing of the highest obtainable interferogram peak, it is not necessary that an interferogram signal be present for alignment to begin. The technique is thus particularly useful when cooling interferometers from room temperature (273° K) to liquid nitrogen temperature (77° K) or colder causes large displacement of optical elements, or when mechanical shock results in similar displacement.
