In this study, multipoint sensing techniques using multimode interference-based fiber-optic sensors were investigated. Here, systems were operated using a wavelength-selective optical filter and a defined-wavelength laser light from an integrable tunable laser assembly (ITLA). By changing the wavelength of the ITLA, measurement of the multipoint refractive index was achieved with high sensitivity.
