ABSTRACT:
An improved laser gyro dither mechanism utilizing a three-spring suspension system which not only isolates dither vibrational energy generated within the gyro and prevents that energy from passing to the mounting case of the laser, but which, additionally, eliminates possible pendulous action by the suspended gyro mechanism. The gyro's ring laser is mounted about a center post in its case. A first spring member is connected between the ring laser an the center post at the top of the post. A second spring member is connected between a counterweight and the centerpost on the bottom of the post. A third spring member is connected between the ring laser and the counterweight on the bottom of the post to complete the suspension system.
