【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 0.1 με.更多还原
