Special Issue on Fiber-Optics. Fiber Sensors for Gas Detection.

PAPER Special Issue on Optical Fiber Sensors

distributed sensings on temperature and strain have been extensively investigated based on Raman [1] and Brillouin [2] scattering methods, respectively. During the course of our developments on a new sensor which can work as one of sensing elements for multi-point detection using a Rayleighscattering based OTDR through an optical fiber network, a hetero-core fiber optic sensor was exploratively...

Sensors based on optical fibers present several advantages over electronic sensors and great research efforts have been made in recent years in this field. The present paper reports the current trends...

Microsphere and Fiber Optics based Optical Sensors

Introduction to fiber optics: Sensors for biomedical applications

The paper focuses on the introduction of fiber optics, a fusion of science and engineering and describes the materials generally used for its construction along with the procedure used to design the fibers. It gives an idea of the materials used for the construction along with the pros and cons associated with them and various factors governing the emission of ultraviolet, infrared or visible r...

Fiber Optics-based Cylinder Pressure Sensors for Advanced Engine Controls

This paper presents the design, applications, and performance of the miniature fiber optic-based cylinder pressure sensor which has targeted advanced engine controls requiring high accuracy pressure information. Three types of sensor packages are described currently utilized in prototype closed loop control systems for diesel, gasoline, and dual fuel engines: glow plug with the heater-mounted s...
