Abstract
Two of the three reflecting mirrors in a ring laser gyroscope are provided with transducers permitting the mirrors to control the ring laser gyroscope laser path. The third mirror is partially reflecting to permit some cavity radiation to exit. The radiation includes winking signal components which are related to laser beam lock-in. By controlling the phase difference between the signal components, minimum lock-in may be achieved.
