RING LASER GYROSCOPE WITH DOPPLER MIRRORS AND OFFSET ACTUATORS

摘要

An equilateral triangular ring laser gyroscope contains drivers to vibrate two of the mirrors synchronously and oppositely along paths displaced by about 4.27 DEG from the bisector of the vertex angles at which those mirrors are located. The magnitude of displacement is about 0.761 lambda , where lambda is the wavelength of laser radiation. The purpose of the vibration is to reduce the lock-in effect in the ring laser gyroscope.
