Abstract
A ring laser gyroscope (RLG) includes moveable mirrors and a Micro-Electro-Mechanical Systems (MEMS) actuator coupled to the moveable mirrors to cause a respective displacement thereof that induces a phase modulation on counter-propagating light beams relative to one another. The induced phase modulation creates an optical path difference between the counter-propagating light beams corresponding to a virtual rotation that reduces the lock-in of the RLG.
