Claim 1
Independent Claim
99 words
THE METHOD OF MONITORING THE TIME VARIANT ALIGNMENTS OF MAGNETIC MOMENTS OF QUANTUM SYSTEMS IN MAGNETIC FIELDS WHICH COMPRISES THE STEPS OF PRODUCING PRECESSIONS OF THE MAGNETIC MOMENTS OF SAID QUANTUM SYSTEM IN A MAGNETIC FIELD, IRRADIATING SAID QUANTUM SYSTEM WITH OPTICAL RADIATION HAVING A PROPAGATION DIRECTION WITH REFERENCE TO SAID FIELD SUCH THAT THE INTENSITY OF SAID RADIATION WHICH PASSES THROUGH SAID QUANTUM SYSTEMS WITHOUT ABSORPTION IS MODULATED AT A FREQUENCY WHICH VARIES IN ACCORDANCE WITH THE FREQUENCY OF SAID PRECESSIONS, AND DETECTING THE INTENSITY MODULATION OF THE NON-ABSORBED OPTICAL RADIATION WHICH HAS PASSED THROUGH SAID QUANTUM SYSTEMS.
