Fiber Optical & Ring Laser Gyro working principle. What is Sagnac effect ?

Описание к видео Fiber Optical & Ring Laser Gyro working principle. What is Sagnac effect ?

Classification Of Gyroscopes by Construction ? Both FOG and RLG are optical gyros, all based on the Sagnac effect. The difference is that one propagates in the fiber and one propagates in the cavity, and the ring laser gyro has high precision. The principle of fiber optic gyro is similar to ring laser gyro, but the various optical effects that actually occur make this method difficult to achieve.
