We have developed a four-channel optically pumped atomic magnetometer for
magnetoencephalography (MEG) that incorporates a passive diffractive optical
element (DOE). The DOE allows us to achieve a long, 18-mm gradiometer baseline in
a compact footprint on the head. Using gradiometry, the sensitivities of the
channels are < 5 fT/Hz(1/2), and the 3-dB bandwidths are approximately 90 Hz,
which are both sufficient to perform MEG. Additionally, the channels are highly
uniform, which offers the possibility of employing standard MEG post-processing
techniques. This module will serve as a building block of an array for magnetic
source localization.
