A compact, high performance atomic magnetometer for biomedical applications.

چکیده
We present a highly sensitive room-temperature atomic magnetometer (AM), designed for use in biomedical applications. The magnetometer sensor head is only 2 × 2 × 5 cm3 and is constructed using readily available, low-cost optical components. The magnetic field resolution of the AM is <10 fT Hz–1/2, which is comparable to cryogenically cooled superconducting quantum interference device (SQUID) magnetometers. We present side-by-side comparisons between our AM and a SQUID magnetometer, and show that equally high quality magnetoencephalography and magnetocardiography recordings can be obtained using our AM.

Erratum: Vectorized magnetometer for space applications using electrical readout of atomic scale defects in silicon carbide
Magnetometers are essential for scientific investigation of planetary bodies and are therefore ubiquitous on missions in space. Fluxgate and optically pumped atomic gas based magnetometers are typically flown because of their proven performance, reliability, and ability to adhere to the strict requirements associated with space missions. However, their complexity, size, and cost prevent their a...
متن کاملCross-validation of microfabricated atomic magnetometers with superconducting quantum interference devices for biomagnetic applications
We compare the performance of a chip-scale atomic magnetometer CSAM with that of a superconducting quantum interference device SQUID sensor in two biomedical applications. Magnetocardiograms MCGs of healthy human subjects were measured simultaneously by a CSAM and a multichannel SQUID sensor in a magnetically shielded room. The typical features of MCGs are resolved by the CSAM, matching the SQU...
متن کاملA High-Sensitivity Tunable Two-Beam Fiber-Coupled High-Density Magnetometer with Laser Heating
Atomic magnetometers (AM) are finding many applications in biomagnetism, national security, industry, and science. Fiber-coupled (FC) designs promise to make them compact and flexible for operation. Most FC designs are based on a single-beam configuration or electrical heating. Here, we demonstrate a two-beam FC AM with laser heating that has 5 fT/Hz1/2 sensitivity at low frequency (50 Hz), whi...
متن کاملChip - Scale Room - Temperature Atomic Magnetometers for Biomedical Measurements
We describe a portable four-channel array of chip-scale atomic magnetometers in a flexible flying-lead configuration. These microfabricated, uncooled sensors with volumes below 1 cm 3 demonstrate sensitivities around 100 fT/Hz 1/2 and bandwidths of several hundred hertz. Performance limits are discussed, as the design is easily scalable to different sensor sizes and large arrays. Initial measur...

We present a portable four-channel atomic magnetometer array operating in the spin-exchange relaxation-free regime. The magnetometer array has several design features intended to maximize its suitability for biomagnetic measurement, specifically foetal magnetocardiography, such as a compact modular design and fibre-coupled lasers. The modular design allows the independent positioning and orient...
