Abstract
A self-correcting assemblable optical fiber sensing system for a displacement field and a correction method thereof are provided. The system includes multiple assemblable flexible optical fiber sensing devices for measuring displacement field; multiple inclination angle self-sensing connection devices for connecting between assemblable flexible optical fiber sensing devices, and an optical fiber demodulation device for obtaining strain data of the assemblable flexible optical fiber sensing devices and two-axis inclination angle data of the inclination angle self-sensing connection devices, and correcting the displacement field measured by the assemblable flexible optical fiber sensing devices. The assemblable flexible optical fiber sensing devices are connected between the inclination angle self-sensing connection devices, and the optical fiber demodulation device is connected to a free end of the inclination angle self-sensing connection device. In this situation, two-dimensional displacement field monitoring of the large-scale structure can be realized.
