Abstract
A torsional hinge is axially mounted within a central bore of a ring laser gyroscope body. The hinge comprises a plurality of angularly spaced wing sections having generally radially extending slits therein for permitting torsional motion of the gyroscope about the hinge. A plurality of spaced arcuate segments bridge a gap between the wing sections and the confronting surface of the bore and are cemented to the surface for securement of the hinge. By properly dimensioning and positioning the subtending contact areas of the hinge within the bore, the effects of thermal expansion of the hinge are minimized thereby inhibiting distortion of the gyroscope body as well as path length changes with temperature.
