Restoring Velocity Immunity via Dynamic Mirror Compensation in a Large-Area Dual-Atom-Interferometer Gyroscope
Jie Gu, Yin-fei Mao, Zhan-Wei Yao +10
We propose and demonstrate a dynamical mirror compensation scheme to restore velocity immunity in a large-area dual-atom-interferometer gyroscope. In an ideal Mach-Zehnder configur…
Highly stable modular-assembled laser system for a dual-atom-interferometer gyroscope
Chuan Sun, Si-Bin Lu, Min Jiang +8
Operating atom-interferometer gyroscopes outside a laboratory environment is challenging primarily owing to the instability of laser systems. To enhance the thermal stability of fr…
Compact multi-channel radio frequency pulse sequence generator with fast switching capability for cold atom interferometers
Min Jiang, Si-Bin Lu, Yang Li +10
Cold atom interferometers have matured to a powerful tool in fundamental physics research, and they are currently on their way from realizations in the laboratory to applications i…
Self-Calibrated Atom-Interferometer Gyroscope by Modulating Atomic Velocities
Hong-Hui Chen, Zhan-Wei Yao, Ze-Xi Lu +10
Atom-interferometer gyroscopes have attracted much attention for their potential superior long-term stability and extremely low drift. For such high precision instrument, a self-ca…
Self-Alignment of a Large-Area Dual-Atom-Interferometer Gyroscope Using Parameter Decoupled Phase Seeking Calibrations
Zhan-Wei Yao, Hong-Hui Chen, Si-Bin Lu +9
We realize a Mach-Zehnder-type dual-atom-interferometer gyroscope with an interrogation arm of 40 cm length and the interference area up to 1.2 cm. The precise angular alignmen…
