A ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation.

Ring laser gyroscopes are lightweight, compact and self-contained, which allows for no friction. This is a major benefit, especially for inertial navigation systems (INS). Having no moving parts and being lightweight, prevents them from producing extra drag for …

Ring lasers are composed of two beams of light of the same polarization traveling in opposite directions ("counter-rotating") in a closed loop. Ring lasers are used most frequently as gyroscopes (ring laser gyroscope) in moving vessels like cars, ships, planes, and missiles.

A Ring Laser Gyro (RLG) is a gyroscope that uses the optical Sagnac effect to sense rotation. Most commonly, the RLG is filled with a gas, such as Helium Neon (HeNe), and electrodes are used to excite light waves traveling in the clockwise (CW) and counterclockwise (CCW) directions.

In a ring laser gyroscope, the two counter-rotating beams are channeled to a photo detector. If the vehicle is not rotating, the beams remain in phase. If rotation is occurring, one beam...

A ring laser is a laser with a ring resonator as its laser resonator. In contrast to a standing-wave (or linear) laser resonator, such a ring resonator does not have any end mirrors, hit with normal incidence, and it allows for two different propagation directions of the intracavity light.
