Abstract
An application of mechanically created long-period fiber gratings as sensitive bend sensors in structures and other areas is suggested. A resonance splitting of about 10 nm is observed under a maximum bend curvature of 0.4 m–1, producing a bend sensitivity of 25 nm/m–1. The design features of the experimental setup developed for the realization of mechanically created long-period fiber gratings and measurement of their output spectrum under different bend curvatures are discussed.
