One of the main goals in fiber optic sensor technology is to multiplex together a high number
of sensors in the same network in order to share expensive terminal equipment and develop …

An optical fiber liquid-level sensor based on an extrinsic Fabry-Perot (FP) cavity is proposed
and demonstrated. The FP cavity consists of the end of the single-mode optical fiber and the …

We report here a low-cost evanescent field wave fiber optic temperature sensor. The amount
of rays guided along the fiber probe is the result of the absorption of evanescent waves …

Different multiplexing techniques for passively addressing fiber-optic sensors and
compensation schemes for overcoming the undesirable optical signal losses to provide self …

An improved ring resonator self-referencing technique in a new reflection configuration for
remote fiber-optic intensity sensors is demonstrated using fiber Bragg gratings. Sensor …

We examine concentration of solution with the help of a set-up with two experimental fiber
optic sensors, utilizing intensity modulation by reflection as well as evanescent wave …

A short review of self-reference techniques for remote fiber-optic intensity sensors and
possible integration in multiplexing sensor networks is reported. Special focus is given to …

We present a fiber-optic refractometer with intensity-type transducer which can operate
remotely via long fiber-optic cables. This version of the refractometer is intended for …

In this paper, we report on design rules for optimizing the response of intensity sensors
embedded in ring resonators (RR) as part of a frequency based self-referencing method …

A simultaneous interrogation system for an intensity-type sensor, fiber Bragg grating and an
extrinsic Fabry–Perot interferometer is demonstrated. The three types of sensors occupy …
