Abstract

Det beskrives et coriolisgyroskop (1') som har en første og en andre resonator (701, 702), som hver er i form av et koblet system omfattende en første og en andre lineær oscillator (31, 32, 41 og 42), i hvilket tilfelle den første resonatoren (701) sammen med den andre resonatoren (702) kan fås til å oscillere i antifase med hensyn til hverandre langs en felles oscillasjonsakse (72). Et system som er koblet på denne måten har den fordel at det er mulig å måle rotasjonshastigheten og akselerasjoner samtidig, og at den er ufølsom mot forstyrrelsespåvirkninger, for eksempel eksternt eller internt virkende vibrasjoner.
