G01C19/725 - CPC Classification

Classification description:

Gyroscopes; Turn-sensitive devices using vibrating masses; Turn-sensitive devices without moving masses; Measuring angular rate using gyroscopic effects; Turn-sensitive devices without moving masses; Gyrometers using the Sagnac effect, i.e. rotation-induced shifts between counter-rotating electromagnetic beams with counter-rotating light beams in a passive ring, e.g. fibre laser gyrometers using nxn optical couplers, e.g. 3x3 couplers
