Abstract

We propose and experimentally demonstrate a compact in-line micro-fiber inclinometer based on deformation of FBG, where the micro-fiber FBG beam is fabricated by special chemical etching method and the fiber pendulum is gained by splicing a section of hollow core fiber filling with tin to the end of the micro-fiber beam. The experiment results show that as the inclination angle increasing from00 to 200, the increments of the transmission loss and Bragg wavelength of the sensor are 1.81dB, and 0.035nm, respectively. Simultaneously, the change of the bandwidth at -25dBm increases linearly from 0.86nm to 1.048nm and the bandwidth sensitivity to inclination angle is 7.24pm/deg. On the other hand, temperature cross issue is solved by monitoring the bandwidth at -25dBm because the bandwidth sensitivity to temperature is 0.089pm/from 20° to 200°. © 2013 SPIE.
