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

NIST Inventors

John Kitching and Elizabeth Donley

An inertial point-source matter-wave atom interferometer gyroscope includes an analyzer that receives fringe images of gyroscope atoms and includes: a first fringe image that includes a first fringe phase, a second fringe image that includes a second fringe phase; and a third fringe image that

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

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
