Abstract

Angular measurements having a resolution of a few tenths of a microradian were made by using a system based on an acousto-optic beam deflector. The overall dynamic range of this system was approximately 1.8 mrad. The linearity of the relationship between the angle of deflection and changes in the rf driving signal was examined by an interferometric arrangement, and various possible limitations to accuracy were investigated. Applications for the technique are envisaged in long-path intersatellite communication systems, experiments involving small mechanical deflections such as metrological mass measurements, and tunable dye-laser scan calibrations in high-resolution spectroscopy.
