摘要：
The measurement method of strain inside strong pulsed magnet has been demonstrated by using embedded fiber Bragg gratings. 23 FBGs were embedded in a strong pulsed magnet of 60 Tesla. The strain inside the magnet was successfully measured in a 10-millisecond pulse time by adopting high speed demodulation devices in normal temperature and liquid nitrogen temperature, respectively. The research achievement is significant for the further development of strong pulsed magnetic field technology.
