| Abstract: | The winding technology of fiber coil used in fiber optic gyroscope was demonstrated. The principle and application of Brillouin Optical Time Domain Reflectometer (BOTDR) were introduced. Under different condition, the stain distribution of a polarization maintain fiber and fiber coil were measured and analysed firstly with a BOTDR instrument and the process defect in fiber coil were found and positioned. The results show that the defects in fiber and fiber coil can be found and controlled effectively with BOTDR. |
