Outline of Final Research Achievements

We will develop a novel strain sensor system to boost optical fiber sensor technology for sophistication of civil engineering / construction structure management to popularization level.
An optical fiber wound in a circle is connected to an invar line, and its expansion and contraction is converted into an angle change. We develop a completely new sensor that measures the change in polarization of light passing through the fiber with the Stokes parameter when the sensor angle changes due to strain and converts it into the amount of strain.
In the method using function fitting to the measured Stokes parameters and using the approximate curve, a sufficient sampling speed, and very accurate was obtained even when comparing the actual sensor angle and the calculated angle.
