Minig: a compact multi-axis atom interferometer

Gravimeters using atom interferometry have been successfully applied for metrology, geology, mineral exploration, and other applications. Miniature atom interferometers with the ability of multi-axis sensing would open up applications in inertial navigation, such as aviation, robotic aircraft, and other emerging technologies. However, state-of-the-art atom interferometers are too complicated to operate in a miniature package.

We are developing an extremely simple, compact atom interferometer that will sense at least four axes of accelerations, gravity, and rotation simultaneously. With a simple and rugged design and low power consumption, it will be able to transport our minig from the well-controlled laboratory to real industrial field applications.
