摘要
对聚合物封装的光纤光栅的压力敏感特性进行了实验研究，在１０ＭＰａ的压力范围内，光纤光栅中心波长的相对变化与外界压力成良好的线性关系，由于聚合物基底的带动作用，两种不同聚合物封装的光纤光栅的压力灵敏度分别为－３．９６×１０－５／ＭＰａ和－６．２８×１０－５／ＭＰａ，提高为裸光栅的２０倍和３１．７倍．
It is
investigated experimentally the pressure properties of fiber grating packaged with polymer
jacket.In the range of 10MPa,the fractional wavelength shift of fiber grating is linear with the
pressure.Due to the diving effect of the polymer medium,the sensitivity of the grating packaged
with two kinds of polymer is -3.96×10 -5 /MPa and -6.28×10 -5 /MPa respectively,which is
20 and 31.7 times higher than a type value for a normal fiber grating
