Abstract
A ring laser gyro has tilting mirrors that can be sinusoidally tilted and therefore cause the optical path defined by the mirrors to be sinusoidally rotated (dithered). The dithering of the mirrors takes place in an angular motion. The mirrors are driven by the same drive signal therefore eliminating the need to precisely control the amplitude and phase.
