good repeatability, high linearity, and ease of installation is proposed with a support of …

An intensity-modulated side mode-based fiber Bragg grating (FBG) refractive index (RI)
sensor is demonstrated. The feasibility is based on Fresnel reflection from the end-face of …

This paper presents and numerically analyzes a refractive index sensor based on side-
polished D-shaped two-channel photonic crystal fiber (PCF) and surface plasmon …

In this work, the design, construction, and testing of an intensity-modulated refractive index
(RI) sensor based on fiber optics which distal end is mechanically polished at 45°, forming a …

In this paper, a remote water salinity measurement system based on a simple and low-cost
intensity based side-polished fiber-optic U-shaped sensor is presented. The sensor system …

We report here a novel optical technique for the continuous measurement of the level and
the volume of transparent liquids in a cylindrical container. This measurement technique is …

This paper reports the application of doped nanocrystalline diamond (NCD) films—nitrogen-
doped NCD and boron-doped NCD—as reflective surfaces in an interferometric sensor of …

Owing to industrial applications, a fiber optic displacement sensor is introduced to determine
the concentration of hydrocarbons in water. Hydrocarbon is organic water pollution. It can …
