Rotational seismology is a key technology for advancing multidimensional and high-precision seismic sensing. This technology is focused on a self-developed FOG, establishing a sensing system for the rotational motions of seismic waves and enhancing both the dimensionality and accuracy of earthquake sensing. The FOG seismometer features high-precision rotational measurement, interference resistance, portability, and scalability, showing capabilities to build advanced seismic monitoring networks.

Rotational information induced by seismic motion is critical for understanding earthquake dynamics, crustal stress states, and structural responses of buildings. Our team is the first to conduct a long-term field deployment of fully homemade high-precision FOGs in Taiwan for seismic sensing. This approach effectively overcomes the limitations of traditional seismometers in capturing high-frequency or weak rotational signals, enabling multidimensional seismic sensing with great scientific value.

The developed FOG seismometers not only advance research in seismology but also hold significant industrial values, including earthquake monitoring, civil engineering, automation, vibration protection for such as semiconductor fabs, energy, defense, aerospace, geological exploration, and smart disaster prevention. Our team aims to promote its application in smart sensing, unmanned vehicles, and low Earth orbit satellite industries through technology transfer and academia-industry collaboration.
