Inertial Point-source Matter-wave Atom Interferometer Gyroscope And Extracting Inertial Parameters

NIST Inventors

John Kitching and Elizabeth Donley

The invention, Simple, High dynamic range, and Efficient Extraction of Phase map (SHEEP), is a technique to directly measure the atom phase gradient pattern in a point source matter-wave atom interferometer gyroscope. By making measurements at several interferometer phase set points, a full

Process For Making Alkali Metal Vapor Cells

NIST Inventors

John Kitching

Making alkali metal vapor cells includes: providing a preform wafer that includes cell cavities in a cavity layer; providing a sealing wafer having a cover layer and transmission apertures; disposing a deposition assembly on the sealing wafer; disposing an alkali metal precursor in the deposition

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

Prototype microchip device combining NIST's miniature atomic magnetometer with a fluid channel

Integrated Microchip Incorporating Atomic Magnetometer and Microfluidic Channel for NMR and MRI

NIST Inventors

John Kitching

This technology is a device that integrates a microfluidic channel and an alkali vapor cell on a microchip-like platform. In conjunction with a near resonant laser beam, the alkali vapor cell forms the basis for an atomic magnetometer, competing with (or even exceeding) the sensitivity of

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 Magnetometer and Method of Sensing Magnetic Fields

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

Simple, High Dynamic Range, And Efficient Extraction Of Phase Map (SHEEP) For Point Source Atom Interferometry

NIST Inventors

John Kitching and Elizabeth Donley

Atom interferometer gyroscopes use cold atoms and a series of laser pulses to measure the acceleration and rotation of a moving system and therefore can be used for inertial navigation. Some atom interferometers make measurements by imaging the atoms onto a CCD. Analyzing the atom spatial pattern
