METHOD AND APPARATUS FOR PRESETTING THE POSITION OF A PIEZOELECTRIC ACTUATOR FOR CONTROLLING THE LENGTH OF THE LASER BEAM OF A RING LASER GYROSCOPE

摘要

METHOD AND APPARATUS FOR PRESETTING THE POSITION OF A PIEZOELECTRIC ACTUATOR 22 USED FOR CONTROLLING THE TRAJECTORY LENGTH OF LASER BEAM 14 OF A RING LASER GYROSCOPE. /P P THE CONJUNCTION LENGTH CONTROLLER '' INVENTION MINIMIZES THE NECESSARY ACTUATOR 22 NECESSARY MOVEMENT BY PRE-ESTABLISHING THE POSITION OF THE ACTUATOR ACCORDING TO THE AMBIENT TEMPERATURE OR STARTING THE LASER GYROSCOPE TO PREDICT VARIATIONS IN THE LENGTH OF THE TRAJECTO VARIATIONS IN THE AMBIENT TEMPERATURE AND / OR THE HEATING EFFECT WHEN THE GYROSCOPE IS ON.
