摘要：
The subject of this work is the strain characteristic of fiber-optic flexural disk accelerometer. In the presented investigation, the strain distribution of flexural disk is studied and the result shows that the position of fiber coil has a significant effect on the strain of fiber coil. We simulated the strain distribution of fiber-optic flexural disk accelerometer that based on multilayer fiber coils and on the optimized position. In experiment, corresponding sample accelerometer is fabricated and tested in the Brillouin Optical Time-Domain Analysis. The experimental result is in good agreement with the simulated result, provides this theoretical approach is effective in designing the fiber-optic flexural disk accelerometer.
