摘要
The transverse-load characteristics of a twisted long-period fibre grating (LPFG) written by high-firequency CO2 laser pulses are investigated for the first time to the authors' knowledge. It is observed that such a twisted LPFG can weaken the strong orientation-dcpendence of the transverse load and enhance the transverse-load sensitivity considerably, when compared with a torsion-free LPFG, offering the potential for use as a dynamic load sensor by means of simple intensity detection.
