Resumo: | A simple optical inclinometer based on a phase-shifted Bragg grating in a taper configuration is proposed. Two phase-shifted fiber Bragg gratings were fabricated using a DUV femtosecond laser technique in the taper region, with taper waist diameters of 30 mu m and 50 mu m. Both sensing heads were compared based on their response to angle and strain. Whereas the higher diameter sensor yielded a higher sensitivity to curvature (23.8 +/- 0.3 pm/degree), the lower diameter one was more sensitive to strain (8.94 +/- 0.04 pm/mu epsilon). |
