摘要：

High-performance angular accelerometers are essential for precise dynamics control of aircraft, satellites, etc. Here, we propose, for the first time to the best of our knowledge, an angular accelerometer based on a dual-polarization fiber-optic Sagnac interferometer, which exhibits relatively high sensitivity and a broad bandwidth. The experimental results show that the angular accelerometer achieves a flat fre-quency response in the bandwidth range of 0.01-100 Hz. root The sensitivity reaches 6.6 x 10-8 rad/s2/ Hz. In addition, the proposed fiber-optic angular accelerometer does not rely on any mechanical structure and has strong environmental adaptability. This research provides a feasible solution for the design and implementation of new high-performance angular accelerometers, which contributes to their devel-opment in the fields of inertial navigation and rotational seismology.(c) 2023 Optica Publishing Group
