Since the first publications related to microstructured optical fibers (MOFs), the development
of optical fiber sensors (OFS) based on them has attracted the interest of many research …

In this paper, an optical fiber interferometric humidity sensor is presented. The device
consists of 1 cm-long segment of photonic crystal fiber (PCF) spliced to standard single …

The paper presents an approach to noninvasively measure pulse wave delay and velocity
by means of two multiplexed fiber-optic Fabry-Perot interferometric sensors interrogated by …

In this paper, a new optical fiber sensor for relative humidity measurements is presented and
characterized. The sensor is based on a SnO 2 sputtering deposition on a microstructured …

The development of an optical fiber refractometer by hydrogen fluoride etching and
sputtering deposition of a thin-film of indium tin oxide on a single-mode-multimode-single …

The combustion of coal wastes resulting from mining is of particular environmental concern,
and the importance of proper management involving real-time assessment of their status …

The performance of E-SMS (Etched Singlemode-Multimode-Singlemode) optical fiber
structures as immunosensors has been assessed by the implementation of antibody/antigen …

The paper is aimed at improving the efficiency of signal processing for intermode fiber-optic
interferometers. To do so, we propose to use the MUSIC algorithm. It is shown that the use of …

In this paper we analyse the recent advances on sensors based on photonic crystal fibres
(PCFs) and discuss their advantages and disadvantages. Some innovative approaches to …

In this work, the performance of five different fiber optic sensors at cryogenic temperatures
has been analyzed. A photonic crystal fiber Fabry-Pérot interferometer, two Sagnac …
