A Novel Chirped Fiber Grating Sensor for Strain Detection

In this paper, a novel strain sensor based on chirped fiber grating with temperature compensation is presented. The proposed strain sensor uses double chirped fiber gratings. The temperature compensation exploit the principle that the wavelength shifts of these two chirped fiber gratings induced by temperature is consistent. This strain sensor is demodulated by the light intensity detection with low cost. Furthermore, the strain sensor is simulated in the end of this paper.
