[...] certains laboratoires ont étudié divers dispositifs de mesure des rotations absolues ne présentant qu'une analogie assez lointaine avec les gyroscopes classiques. Ce sont les gyroscopes à vibrations, dans lesquels le mouvement de rotation de la toupie est remplacé par le mouvement de va-et-vient d'éléments mécaniques; les gyroscopes nucléaires, dans lesquels le spin du noyau atomique est utilisé comme référence spatiale; les gyroscopes optiques, exploitant les propriétés de la lumière cohérente [...]
