| description | The invention relates to a fiber-optic accelerometer (10) comprising: - an optical fiber (11, 35, 50) having a free end, said free end being caused to oscillate under the influence of acceleration; -a light source for emitting visible, ultraviolet or infrared light into the optical fiber (11, 35, 50) at an end of the fiber (11, 35, 50) opposite the free end; - a mirror (14, 24, 45), which is arranged to reflect part of the light exiting the free end back into the optical fiber (11, 35, 50); and - a detection device for capturing reflected light at the end of the fiber (11, 35, 50) opposite the free end, the core of the optical fiber (11, 35, 50) having a Bragg grating in the free end.
本发明涉及种光纤式加速度传感器(10)，其具有：-光学纤维(11、35、50)，所述光学纤维具有自由端部，其中，所述自由端部在加速度影响下产生振动，-光源，所述光源用于在纤维(11、35、50)的背离自由端部的端部处将可见的、紫外的或者红外的光线发射到光学纤维(11、35、50)中，-镜子(14、24、45)，所述镜子布置用于将部分从自由端部射出的光线反射到光学纤维(11、35、50)中，-用于接收纤维(11、35、50)的背离自由端部的端部处的反射光线的探测装置，其中，-光学纤维(11、35、50)的纤芯在自由端部中具有布拉格光栅。 |
