将三个布拉格光纤光栅组成的传感器空间阵列埋置于在硅橡胶正立方体模块的内部,其分别位于x、y、z轴的方向,当模块受到外力时,利用每个光栅对径向应变感测的特性,观测三个光栅反射光波峰的漂移,实现了对施加外力产生应变的方向监测.经过验证,测量结果与施加外力方向基本一致. The sensor space array composed of three Bragg fiber gratings is embedded in the interior of the silicone rubber cuboid module in the directions of x, y and z axes respectively. When the module is subjected to external force, the radial strain sense Measured the characteristics of the three grating reflection peak shift, to achieve the application of external force to generate strain monitoring.After verification, the measurement results and the direction of external force is basically the same.
