[期刊论文] 作者:ZhihangHan,CuitingSun,XirenJin,HangJiang,ChongYao,ShuoZhang,WeiliangLiu,TaoGeng,FengPeng,WeiminSun,LiboYuan, 来源:ChineseOpticsLetters 年份:2018
A torsion sensor based on the near-helical (NH) long period fiber grating (LPFG) is fabricated by using a high frequency pulsed CO2 laser. Each groove of the NH-LPFG is spirally written in the four sides of a single-mode fiber. The NH-LPFG ......
