摘要：

Fiber Bragg grating(FBG)-based strain and temperature sensor arrays were embedded into the concrete structure in order to provide real-time information on its strain and temperature distribution. The sensors were wavelength-multiplexed along a single fiber. The temperature and strain sensors were specially designed and optimized for their measurands. The calibration experiments of those FBG sensors, and parameter monitoring during the structural curing processes were also presented in this paper. These fiber optic strain and temperature sensors show many advantages over the traditional electrical strain gauges and thermocouples.
