Paper Abstract

This paper describes measurement algorithms and control procedures that can be effectively applied to the automation of an alignment procedure for paraboloidal optical mirrors. Interferometric alignment of an off-axis paraboloidal optical mirror can be a tedious and labor- intensive process. We review a previous solution to the alignment problem that employs a corner-cube retroreflector and present a method of automating this process using an imaging interferometer coupled to a processing system that controls a set of actuators. The relevant image-processing algorithms are described, and the actuator-control system is discussed. Methods of extending this solution to the automatic alignment of other aspheric optics are explored.
