Fiber optic sensing technology is a well-known technique for measuring vibration, strain distribution and temperature distribution of structures. In this study, BOCDA (Brillouin Optical Correlation Domain Analysis) was used to measure the strain of an object that resembled a structure vibrating at high speed. The shape of the object calculated from the measurement value was represented as a digital twin in virtual space.
