The difference between laser gyro and fiber optic gyroscope
Oct 19, 2018

The basic components of the laser gyro are helium neon, total reflection mirror, and half mirror. Laser gyro combines cutting-edge technology such as light, machine, electricity and calculation. It covers a wide range of fields, including land, sea and air. Laser gyros is one of the important indicators to measure the development level of a country's optical technology. The working principle is that in the closed optical path, the two lights transmitted by the same light source in the clockwise direction and the counterclockwise direction interfere with each other, and by detecting the phase difference or the change of the interference fringes, the rotational angular velocity of the closed optical path can be measured.

Fiber optic gyroscope is a kind of fiber optic sensor gyroscope used for inertial navigation, which means "rotation indicator", which is a kind of sensor that sensitive angular velocity and angular deviation. The fiber optic gyroscope is a gyroscope in a broad sense, and is a sensor with a gyro effect based on the principle of modern physics. Because it has no moving parts - high speed rotor, called solid state gyroscope. This new all-solid-state gyroscope will become the leading product of the future with broad development prospects and application prospects.
