对光纤布拉格光栅（FBG）换能器中应变梯度引起的光谱展宽进行了实验研究。导出了描述圆形几何换能器中测量诱发应变梯度的封闭形式分析结果，该结果允许实验证明新的FBG键合方法，该方法消除了频谱展宽，并应导致先进的基于FBG的换能器的发展。
An experimental investigation of strain gradient induced spectral broadening in fibre Bragg grating (FBG) based transducers is carried out. Closed form analytical results describing measurand induced strain gradients in circular geometry transducers are derived, which allow experimental demonstration of novel FBG bonding approaches which eliminate spectral broadening and should lead to the development of advanced FBG based transducers.
