Abstract

In this paper, we demonstrate a Talbot-Lau interferometer with magnetically guided Cesium atoms for inertial sensing using both three-pulse and prolonged four-pulse interferometer schemes. The recoil frequency of the Cesium atoms and the acceleration along the waveguide symmetry axis are measured. An acceleration measurement uncertainty of 7 mGal is achieved. We also realize an enclosed area of 0.018 mm2 for rotation sensing. The system limitations and its advantages are also discussed.

Atom interferometry in a moving guide

Saijun Wu, Edward Su, Mara Goff Prentiss

We demonstrate a current-controlled magnetic guide that can transport atoms in the direction perpendicular to the waveguide. We have combined this with a light pulse Talbot-Lau interferometer that splits and recombines atom wavepackets along the free propagation direction of the waveguide, resulting in an interferometric path that encloses area and thus can be used to sense rotation.

Asymmetric Talbot-Lau interferometry for inertial sensing

S. Sala, Marco G. Giammarchi, Stefano Olivares

We study in detail a peculiar configuration of the Talbot-Lau matter wave interferometer, characterized by unequal distances between the two diffraction gratings and the observation plane. We refer to this apparatus as the ``asymmetric Talbot-Lau setup.'' Particular attention is given to its capabilities as an inertial sensor for particle and atomic beams, also in comparison with the classical moir\'e deflectometer. The present paper is motivated by possible experimental applications in the context of antimatter wave interferometry, including the measurement of the gravitational acceleration of antimatter particles. Therefore we focus our analysis on the current state of the art. To support our findings, we have also performed numerical simulations of realistic particle beams with varying speed distributions.

Closed-loop dual-atom-interferometer inertial sensor with continuous cold atomic beams

Zhi-Xin Meng, Pei-Qiang Yan, Shengzhe Wang +3 more

We demonstrate a closed-loop light-pulse atom-interferometer inertial sensor that can realize continuous decoupled measurements of acceleration and rotation rate. The sensor operates with double-loop atom interferometers, which share the same Raman light pulses in a spatially separated Mach-Zehnder configuration and use continuous cold atomic beams propagating in opposite directions from two ${\text{2D}}^{+}$ magneto-optical trappings. Acceleration and the rotation rate are decoupled and simultaneously measured by the sum and difference of dual-atom-interferometer signals, respectively. The sensitivities of inertial measurements are also increased to be approximately 1.86 times higher than that of a single atom interferometer. The acceleration phase shift is compensated in real time by phase locking these interferometers via the Raman laser phases from the sum-interferometer signal, and the gyroscope performance is improved. We achieve long-term stabilities of $6.1\phantom{\rule{0.2em}{0ex}}\text{\ensuremath{\mu}}\text{g}$ and 840 nrad/s for the acceleration and the rotation rate, respectively, using a short interrogation time of 0.87 ms (interference area $A=0.097\phantom{\rule{0.2em}{0ex}}{\text{mm}}^{2}$). This work provides a building block for an atomic interferometer-based inertial measurement unit for use in field applications that require a high data rate and high stability.

Sensitivity of a Point-Source-Interferometry-Based Inertial Measurement Unit Employing Large Momentum Transfer and Launched Atoms

Jinyang Li, Tim Kovachy, Jason Bonacum +1 more

We analyze theoretically the sensitivity of accelerometry and rotation sensing with a point source interferometer employing large momentum transfer (LMT) and present a design of an inertial measurement unit (IMU) that can measure rotation around and acceleration along each of the three axes. In this design, the launching technique is used to realize the LMT process without the need to physically change directions of the Raman pulses, thus significantly simplifying the apparatus. We also describe an explicit scheme for such an IMU.

Six-Axis Inertial Sensor Using Cold-Atom Interferometry

B. Canuel, Florence Leduc, David Holleville +8 more

We have developed an atom interferometer providing a full inertial base. This device uses two counterpropagating cold-atom clouds that are launched in strongly curved parabolic trajectories. Three single Raman beam pairs, pulsed in time, are successively applied in three orthogonal directions leading to the measurement of the three axis of rotation and acceleration. In this purpose, we introduce a new atom gyroscope using a butterfly geometry. We discuss the present sensitivity and the possible improvements.

Quantum sensing of acceleration and rotation by interfering magnetically launched atoms

Clément Salducci, Yannick Bidel, Malo Cadoret +6 more

Accurate and stable measurement of inertial quantities is essential in geophysics, geodesy, fundamental physics, and inertial navigation. Here, we present an architecture for a compact cold-atom accelerometer-gyroscope based on a magnetically launched atom interferometer. Characterizing the launching technique, we demonstrate 700–parts per million gyroscope scale factor stability over 1 day, while acceleration and rotation rate bias stabilities of 7 × 10 −7 meters per second squared and 4 × 10 −7 radians per second are reached after 2 days of integration of the cold-atom sensor. Hybridizing it with a classical accelerometer and gyroscope, we correct their drift and bias to achieve respective 100-fold and 3-fold increase on the stability of the hybridized sensor compared to the classical ones. Compared to a state-of-the-art atomic gyroscope, the simplicity and scalability of our launching technique make this architecture easily extendable to a compact full six-axis inertial measurement unit, providing a pathway toward autonomous positioning and orientation using cold-atom sensors.
