Accelerometer Based on Two-Mode Elliptical-Core Fiber Sensor |
| 摘要 |
Systems and methods are disclosed for sensing acceleration or vibration of a physical object, by placing a two-mode elliptical-core optical fiber on the object; receiving optical signals using photo-detector; and determining acceleration as perturbation effects on the differential phase shift between two spatial modes in each polarization or between two polarization modes in each spatial mode for the two-mode elliptical-core optical fiber. |

1. A method for sensing acceleration or vibration of a physical object, comprising:
placing a two-mode elliptical-core optical fiber on the object; receiving optical signals using photo-detector; and determining acceleration as perturbation effects on the differential phase shift between two spatial modes in each polarization or between two polarization modes in each spatial mode for the two-mode elliptical-core optical fiber. |
