Before And After

A wavelength tunable optical filter based on a fiber Bragg grating using piezoelectric bimorph is realized in this paper, and the tuning condition is theoretically and experimentally analyzed. The Bragg central wavelength of the filter can be easily tuned adopting to a DC voltage. The maximum strain of the central wavelength depends upon the maximum operating voltage, and the tuning range efficiency was as high as 1.2pm/V, the reflectivity, shape and the reflective spectrums of the fiber Bragg grating central wavelength almost keep unchanged before and after tunning. This paper provides a reference for optical fiber Bragg grating tuner.with high efficiency.

On The Road

Based on the fiber Bragg grating sensing technology, a FBG sensor is designed to monitor the dynamic response of asphalt concrete; the sensitivity coefficient of FBG sensor is 1.28pm/με. Through the static load test, the correlation between strain and wavelength variation is 0.1797µε/pm, after second packaged and embedded in SMA-13 asphalt concrete. The instantaneous impact on the road of high-speed vehicles is simulated by using drop hammer. The results are shown that the Sensor can satisfy the requirements of practical applications and succeed in monitoring the dynamic response of asphalt concrete. The monitored signal can reflect the viscoelastic-plastic deformation law of asphalt concrete. The sensor can be used to monitor the dynamic response of asphalt concrete.
