| 摘 要： | 分析了内置式光纤法布里－珀罗磁场传感器的灵敏度及光源线宽对灵敏度的影响。结果表明，光源线宽愈窄，灵敏度愈高；法布里－珀罗腔的反射率在红宽和腔长一定时，有一最佳值。反射率取最佳值时，探测的磁场最小，灵敏度最高。

| Abstract: | The sensitivity of intrinsic fiber optic Fabry Perot (F P) magnetic sensor is studied and the influence of linewidth of light source is discussed. The results show that the linewidth is narrower,the sensitivity will be higher. When the linewidth and the length of F P cavity are chosen, there is an optimum reflectivity. If reflectivity of F P cavity equals the optimum, the magnetic field detected is the minimum and sensitivity is the highest. |
