ABSTRACT:
A method for aligning the light path of a square ring laser gyroscope. First, the path is aligned by translation of adjacent curved mirrors which direct a light beam through a filter-like aperture. Next, the curved mirrors are translated by equal amounts in opposite directions as determined from a measurement of the non-planar condition of opposed mirror mounting surfaces.
