Ring Laser Gyroscope Market Demand by 2030 - MarketWatch

According to the Sagnac effect, a certain rate of rotation induces a small difference between the time it takes light to traverse the ring in the two directions. This introduces a tiny separation between the frequencies of the counter-propagating beams, a motion of the standing wave pattern within the ring, and thus a beat pattern when those two beams interfere outside the ring. Therefore, the net shift of that interference pattern follows the rotation of the unit in the plane of … WebFeb 22, 2024 · Laser ring gyroscopes perform based on the Sagnac Effect.
