Description

technical field [0001] The invention relates to the field of gyroscope teaching experiments, in particular to a coaxially rotatable fiber optic gyroscope experimental device. Background technique [0002] Gyroscope is one of the key components of inertial technology, mainly used for the measurement of angular velocity. Early gyroscopes were electromechanical, and the discovery of the Sagnac effect laid the physical foundation for the advent of optical gyroscopes. Fiber optic gyroscope is a precise physical measurement technology based on optics, which is used to measure the angular motion of sensitive carrier relative to inertial space. The fiber optic gyroscope has a similar mechanical basis to other classic gyroscopes, but it has no rotor and can be used to measure the rotational angular velocity of the carrier relative to the inertial space. During the rotation of the carrier, the Sagnac phase shift causes the light wave interference fringes to move slightly. Thus, the ...

Problems solved by technology

However, the existing teaching equipment can only meet the basic experimental purpose, and cannot reflect the internal signal characteristics of the fiber optic gyroscope.

The existing fiber optic gyroscope teaching device does not have coaxiality, and cannot directly observe the basic working principle of the interior

The current fiber optic gyroscope experimental device cannot be widely used in the teaching field
