Abstract: An optical fiber composite wire strand, a manufacturing method thereof, and a strain measuring method are provided to prevent a fiber bragg grating sensor from being damaged by external shock, by disposing the fiber bragg grating sensor in a through-hole of a first steel wire, thereby exactly measuring the strain rate. In an optical fiber composite wire strand(20), a through-hole(211) is formed on at least one of first and second steel wires(21,22) of the wire strand in a longitudinal direction of the steel wire. The first steel wire is positioned in the center. Six strands of the second steel wires are twisted with surrounding the first steel wire. An optical fiber sensor is disposed in the through-hole. In particular, a fiber bragg grating sensor(10) having grating sensing units arranged on an optical fiber at regular intervals is used.

Abstract: PURPOSE: A wireless structure safety test system is provided to use semi-permanently since the separate power source does not need to be included in a measuring unit. CONSTITUTION: A wireless structure safety test system comprises followings. A laser driver(10) generates the laser and irradiates after altering into the desiring waveform. A photo diode(20) is installed on the structure for the exciting and response measure. An optical signal of the laser from the laser driver is converted into an electric signal. A piezoelectric element(30) is adhered to the structure for the exciting and response measure. A light emitting diode(40) converts the electric signal generated by the response of the structure into the optical signal. A signal processing unit(50) receives the light generated in the light emitting diode in order to diagnose the state of the structure.
