A body dithered laser gyro assembly adapted so that the natural frequency of the assembly can readily be predicted and adjusted. In one embodiment, the laser gyro assembly comprises a base (10), resilient support means (12) mounted to the base, coupling means (30, 40, 50) mounted to the support means, a laser gyro (20) mounted to the coupling means, and drive means (70) connected to the base and to the coupling means. The drive means imparts a dither motion to the coupling means, and the coupling means in turn couples such dither motion to the gyro. The coupling means can include a diaphragm (40) having inner (124) and outer (122) portions, the inner portion of the diaphragm being connected to the drive means, and the outer portion coupled to the laser gyro. The inner and outer diaphragm portions may be connected by a plurality of beams (126) through which the dither motion is coupled. |
