Abstract
Provided are an atomic beam magnetic resonance method and system based on combined separated oscillatory fields. The method includes: generating, by an atomic beam source, two identical atomic beams; performing atomic state purification treatment on the two identical atomic beams to generate two identical state-purified atomic beams; exciting, by zero-phase-difference SOFs, one identical state-purified atomic beam to perform atomic beam magnetic resonance to obtain a first atomic beam magnetic resonance signal; and exciting, by π-phase-difference SOFs, the other identical state-purified atomic beam to perform atomic beam magnetic resonance to thereby obtain a second atomic beam magnetic resonance signal, the zero-phase-difference SOFs and the π-phase-difference SOFs have the same interaction length, the same drift length, and the same oscillatory field strength; and performing subtraction operation on the first atomic beam magnetic resonance signal and the second atomic beam magnetic resonance signal to thereby generate a combined Ramsey magnetic resonance signal.
