A Laser Siderostat.

Abstract

The Mark III Astrometric Interferometer is an instrument designed to improve on our ability to measure angular positions of stars by more than an order of magnitude. The instrument makes extensive use of active optics, digital signal processing and control, and laser metrology. This report describes the efforts of the first year of a four-year program to build the Mark III interferometer, as well as obstacles to technical progress due to Navy administrative procedures. Keywords include: Interferometry, Astrometry, and Active optics.
