摘　　要：就涂覆层对应力长周期光纤光栅谱特性影响进行了研究,发现去涂覆层的应力长周期光纤光栅的谱特性对应力的灵敏度比未去涂覆层的明显的高,且大大改善了其传输谱的特性.By investigating the spectrum of the mechanically-induced long-period fiber grating with fiber jacket, we have discovered the force sensitivity of the mechanically induced long-period fiber grating with fiber jacket increases obviously than that of the mechanically induced long-period fiber grating without fiber jacket, the characteristics of the spectrum improve greatly too.
