A fiber optic sensor for measuring glucose in aqueous solutions
In this paper, the set-up of a multi-mode fiber optic sensor for measuring glucose in aqueous solutions is investigated and evaluated. The basis of this sensor is based on the Fresnel Reflection. In this setup, a helium-neon laser is used as a light source, a fiber optic probe, photocell as detector and a digital multimeter. The statistical analysis of the recorded data shows a highly linear be...

متن کاملDetection of Solvents using a Distributed Fibre Optic Sensor
Introduction: In this Letter an optical fibre sensor capable of making fully distributed measurements of a wide range of solvents is identified. Microbending principles have been used to develop the sensor such that it responds on contact with liquid solvents, typically within 30 seconds of exposure. The sensor incorporates a swelling polymer and optical fibre components that are readily availa...
متن کاملFibre optic pressure sensor and monitoring of structural defects
Pressure induced microbends have been created in a 50 μm graded index multimode optical fibre with spatial periodicity Λ = 4.5 mm, embedded in the sample of araldite. If high pressure is applied directly to optical fibre having microbends, it may break, and if pressure is applied to embedded fibre in a solid structure without microbends, the sensitivity is lower. In this paper, a combination of...
متن کاملFibre-Optic Endoscopy
At last a book on gastrointestinal fibre-optic endoscopy which is not another collection of beautiful photographs, but rather a source of useful information for the practicing endoscopist. This book will be of value to all Endoscopy Units, but particularly to new and developing services. In this rapidly growing field there is need for guidance from an experienced group. Emphasis is placed on th...
