Abstract
We demonstrate repeatable, directional curvature determination to ± 0.05 m-1 using two long period fiber gratings bonded to either side of a metal plate. One grating was utilized for negative, and the other for positive curvature measurements by exploiting an unusual orientation dependence of the grating response.
