Vibrating top

from Wikipedia, the free encyclopedia

A vibration gyroscope ( English Vibrating structure gyroscope , VSG) is a sensor for measuring the rate of rotation and thus the rotation angle of a body in space. The drift of inexpensive sensors amounts to less than 10 ° / h .

A vibration gyro consists of a system that can oscillate, for example an oscillating crystal . If the quartz is rotated perpendicular to the direction of deflection with the angular velocity , the Coriolis force acts

perpendicular to the oscillating system. The distortion can be detected by a piezoelectric pickup .

As with fiber or laser gyroscopes , the word gyro is taken from the gyro instrument , which was traditionally used to determine orientation in space.

The oscillating bulbs in insects work on the principle of a vibrating top.
