Abstract
An optical fiber sensor for detecting curvature of a body/structure comprises a cladding having an outer periphery. A central core receives and transmits light. The central core has Bragg gratings and is positioned in neutral planes of the cladding. Peripheral cores receive and transmit light. The peripheral cores have Bragg gratings and are peripherally positioned in the cladding with respect to the neutral planes. A connection configuration is provided in the outer periphery of the cladding to attach the optical fiber sensor to a body/structure such that the central core and the peripheral cores are in a predetermined orientation with respect to the body/structure to measure curvature of the body/structure.
