Abstract

Et magnetometer omfatter anordninger (44,44,46,48,50) for å modifisere polymerisasjonen av en lysstråle, enten med hensyn til retning eller fra sirkulær polarisasjon med urviseren til sirkulær polarisasjon med urviseren, slik at magnetometeret dermed forblir isotropt. Det kan benyttes til måling av svake magnetfelt.
