在锥形光纤中使用啁啾光纤光栅，演示了一种新型的、温度无关的应变传感器。光栅的有效带宽只依赖于应变，基本上与温度无关。审讯只涉及监控光栅的反向反射强度。在4066 mu epsilon的应变测量范围内，实验实现了0.1%的应变分辨率。
A novel, temperature-independent strain sensor is demonstrated using a chirped fibre grating in a tapered optical fibre. The effective bandwidth of the grating is uniquely dependent on strain and is essentially temperature-independent. The interrogation simply involves monitoring the back-reflected intensity from the grating. A strain resolution of 0.1% over a strain measurement range of 4066 mu epsilon has been experimentally achieved.
