Abstract:Fiber Bragg grating (FBG) based strain sensors have found a variety of applications in the last two decades. Most of these applications utilize the wavelength tuning of FBGs through an axially induced strain because of the high axial load sensitivity in comparison to lateral loading. However, wavelength tuning through lateral or transverse loading is attractive for applications like structural health monitoring, damage detection etc, owing to the flexibility in mounting or embedding the sensor. The wavelength … Show more
