We present a study of noise suppression by fusion in fiber-optic gyroscopes based on the
source-sharing architecture. A theoretical model is proposed for the detailed analysis of the …

Temperature variation degrades the performance of fiber-optic gyroscopes. In terms of a
noise mechanism, we report that thermal phase noise contributes to the dominant effect of …

This article reviews rotational seismology, considering different areas of interest, as well as
measuring devices used for rotational events investigations. After a short theoretical …

Volcano seismology, while its value for surveillance of an active volcano is undebatable, is a
very demanding field when it comes to station deployment, maintenance, and finally …

SUMMARY A new approach is proposed for measuring the dispersion relation of surface
waves in weakly anisotropic media using a single station, which consists of translational …

光纤旋转地震仪具有宽频带, 高灵敏度, 便携等优点, 在地震旋转运动的观测中有着广阔的应用
前景. 光学旋转地震仪的性能会受观测环境噪声的影响, 因此, 在低噪环境下测试仪器的自噪声 …

Volcano‐seismic signals such as long‐period events and tremor are important indicators for
volcanic activity and unrest. However, their wavefield is complex and characterization and …

In the observation of seismic rotational motion, fiber-optic seismometers with wide frequency
band, high sensitivity and portability have broad application prospects. The performance of …

With the development of rotational seismometers, especially the high‐sensitivity optical
seismometers, rotational motions have shown increasing benefits for calculation of …

Measurements of rotations are unique because of their inherent property making them
absolute and without an external frame of reference. This is in contrast to velocity, which …
