 摘要：论述了基于白光干涉的F-P型光纤应变传感器
设计及应White 变信号检测系统的设计。本系统克服了用激
光做光源难以得到干涉条纹,且不易检测的缺点。可
以得到绝对应变,系统检测精度可以达到0.1με,具有
较高的精度。 |

| Design of a New Strain F-P Fiber Sensor Based on Light Interference |
| Abstract：The design of the F-P fiber sensor that based
on the theory of white light interference,and the design
of the signal detect system,and the basic work principle
of the sensor are discussed.The system overcomes the
defect that it is difficult to get the interferemetric stripe with the laser light.The absolute value of the stress change can be obtained,and the precision of detection can reach to 0.1με. |
