Optical alignment of multiple components to a common coordinate system.
An improved method of optical tooling for the determination of angular alignment of randomly oriented multicomponent systems is described. The method was developed for alignment of the Orbiting Astronomical Observatory. A test object is mounted on a precision rotary table and viewed in autocollimation by a first-order theodolite. Azimuth and elevation readings from subject mirrors and relay mirrors, and azimuth readings from a dihedral mirror reference system are transformed into test object coordinates of roll, pitch, and yaw by a computer program. The program uses matrix optics methods. Errors are discussed.
