How does a ring laser gyroscope work?
Two lasers travel in opposite directions on a triangular route. When the gyroscope is rotated on its axis, one of the lasers’ rotational paths is shortened while the other beams’ path is lengthened. The difference in time between the two laser beams is its angular change. PARALIGN consists of three ring laser gyroscopes, enabling is to take measurements in three-dimensional space. (Roll, Pitch, and Yaw).
