The fiber optic sensor measuring system based on the Mech-Zehnder interferometry is developed in the paper. The system can be used for the strain and vibration measurement of engineering structure, and has the advantages: convenient adjusting, stable performance and strong ability of anti-interference, etc. Therefore the fiber optic sensor has been widely used in the engineering field. First the system is introduced into measuring the frequency and amplitude of the vibration subjected to force of the FRP-concrete beam. The fiber optic sensor measuring system and the electronic measuring system are synchronous used for the measurement. The analysis results of fiber optic sensor measurement approximate to the results of electronic strain gauge. Then the system is introduced into experimental stress analysis on the gas pipe, good results is obtained too. The paper provides new technical equipment for the experimental testing of various engineering structure using fiber optic sensor, also establishes the technical foundation of the research of smart structure.

Vibration measurement of CNC milling is one of the used techniques for prediction of tool wear. Monitoring of tool wear is very important since a worn tool will affect machine and workpiece either. We developed a fiber-optic sensor for spindle vibration of CNC face-milling machine. The sensor is based on monitoring loss of light from the fiber core. For this sensor a laser light transmitter circuit, a sense plane construction, and a light receiver circuit are designed. Designed fiber-optic sensor is tested on Taksan TMC 650V face-milling machine. Obtained signals from this sensor is investigated in time domain and frequency domain and showed that it is valuable to tool ware monitoring.

According to the character of fiber-optic coupler, its coupling output is sensitive to the variation of coupling region’s length. A new kind of coupling fiber-optic vibration sensor is presented base on this principle. The theory of coupling single-mode fiber-optic sensor is analyzed. A prototype of fiber optic vibration detection system has been successfully built, including a sensor head, a low-cost control unit and a software package for signal processing with high resolution. The response of fiber-optic sensor and piezoelectric sensor to periodic vibration and shock is measured and the results of the coupling fiber-optic vibration sensor are closely in accordance with high precision piezoelectric sensor. The cross-axis anti-disturbance ability of the fiber-optic sensor is discussed in addition. Experimental results indicate that the coupling fiber-optic vibration sensor has favorable vibration detection capability; it can meet the requirement of vibration measurement.
