best Atomic Magnetometer with high sensitivity

Atomic Magnetometer | SpinMag-I

The Atomic Magnetometer utilizes the spin properties of alkali metal atoms' outer-shell electrons, employing pump lasers as a means of manipulation to induce spin polarization in these atoms. When subjected to an external weak magnetic field, the alkali metal atoms undergo Larmor precession, altering their absorption of detection lasers, thus achieving high-sensitivity magnetic field measurements.

Atomic magnetometers possess characteristics such as high sensitivity, small size, low energy consumption, and portability, which will likely lead humanity into a quantum era in magnetic sensing fields such as scientific research and biomedical applications in the future.

Life Sciences

The atomic magnetometer is primarily applied in magneto- and neuro-magnetic research. By capturing the magnetic field signals of the human body, the atomic magnetometer obtains images of the magnetic distribution of the heart, enabling functional diagnosis and prognostic studies of conditions such as myocardial ischemia, coronary microcirculation disorders, and myocardial diseases. Brain magnetic signals are weaker than heart magnetic signals, yet the quantum spin magnetometer can measure the magnetic fields generated by neural currents, enabling direct imaging of the brain's electrophysiology. This provides valuable information for clinical applications.

 

Physical Geography

The atomic magnetometer captures variations in the Earth's magnetic field with precision, obtaining information about geomagnetic anomalies. This can be utilized for directional drilling in the petroleum industry, monitoring geological hazards, and exploration of mineral resources.

Quantum Diamond Microscope NV Center quantum sensor

CIQTEK Quantum Diamond Microscope (QDM) is a wide-field magnetic resonance based on the principle of spin magnetic resonance in the diamond nitrogen-vacancy center (NV center). The spin quantum state of the NV center luminescence defects is susceptible to the surrounding microwave and static magnetic fields and can be read out using a laser.   Measuring the magnetic or microwave field distribution around the sample using NV centers enables quantitative nondestructive microscopic magnetic imaging with high spatial resolution, a large field of view, a large dynamic range of detectable magnetic fields, and fast imaging speed.   It's also compatible with ambient testing environments to cryogenic & vacuum extreme environments.
