A device for acquiring mechanical variables, namely, angles of rotation, speeds, angular velocities or angular accelerations, comprises at least one fiberglass ring having an elliptical cross section, at least one coupler and decoupler associated with the fiberglass ring, a laser connected to the coupler, and a measuring location connected with the decoupler. The fiberglass ring forms at least two propagation paths wherein the oscillations from the laser rotate in opposite directions. The decoupler decouples the oscillations which are superposed at the measuring location where an evaluation signal is detected.
