Abstract
In this paper we report on the use of a multiple-FBG array inscribed in gradient index multimode CYTOP POF using an efficient femtosecond laser inscription method. The FBG array was mounted across the cantilever as a quasi-distributed sensor and the time-depended wavelength information of each particular FBGpoint sensor was recovered using a commercial spectrometer, designed to operate at 1550nm. We adjusted the degree of damage detection by using different weights suspended in the middle of the flexible beam.
