Time-multiplexed dual atomic magnetometry

A time-multiplexed dual atomic magnetometer, comprising:

• first and second vapor cells located adjacent to a sample cell such that a magnetic field generated by a sample within the sample cell induces Larmor precession of atoms within the first and second vapor cells;
• a first polarimeter that measures a first polarization of a first probe beam after the first probe beam propagates through the first vapor cell, the first polarimeter outputting a first polarization signal indicative of the first polarization;
• a second polarimeter that measures a second polarization of a second probe beam after the second probe beam propagates through the second vapor cell, the second polarimeter outputting a second polarization signal indicative of the second polarization;
• and
• a signal processor that processes alternating data blocks of the first and second polarization signals to generate a single gapless temporal sequence that represents the magnetic field generated by the sample.
