Detection of J-Coupling Using Atomic Magnetometer

NIST Inventors
John Kitching
An embodiment of a method of detecting a J-coupling includes providing a polarized analyte adjacent to a vapor cell of an atomic magnetometer; and measuring one or more J-coupling parameters using the atomic magnetometer. According to an embodiment, measuring the one or more J-coupling parameters

Compact Atomic Magnetometer and Gyroscope

NIST Inventors
John Kitching and Elizabeth Donley
An atomic magnetometer that simultaneously achieves high sensitivity, simple fabrication and small size. This design is based on a diverging (or converging) beam of light that passes through an alkali atom vapor cell and that contains a distribution of beam propagation vectors. The existence of more

Atomic Vapor Cell And Making An Atomic Vapor Cell

NIST Inventors
Christopher L. Holloway , Alexandra (Aly) Artusio-Glimpse , Vladimir Aksyuk , Matt Simons and John Kitching
Research over the past ten years into atomic sensors has allowed for controlled ensembles of room temperature atoms in such a manner that we are able to develop interesting and unique devices. Beside SI traceable E-field probes, other applications range from atom-based receivers to imaging
Fiber magnetometer

Chip-Scale Atomic Magnetometer

NIST Inventors
John Kitching and Vladislav Gerginov
A magnetometer and method of use is presently disclosed. The magnetometer has at least one sensor void of extraneous metallic components, electrical contacts and electrically conducting pathways. The sensor contains an active material vapor, such as an alkali vapor, that alters at least one
