Abstract

Multipoint sensing measurement with fine resolution was developed using multimode interference optical fibers, working as refractive index (RI) sensors. They were operated with a fine calibration technique using a wavelength selective optical filter and defined-wavelength-light from a tunable laser source. Average RI resolution is 4.3 ×10-6 RIU under multipoint sensing conditions.
