Optical router for optical fiber sensor networks based on a liquid crystal cell
(09/04/2003)
Optical fiber sensor networks are evolving rapidly. They are used because of the inert nature of optical fibers allowing no electromagnetic interference and safe applications in inflammable atmospheres; other relevant ...
Time Division Multiplexing Fibre-Optic Liquid Level Sensors using a Nematic 1x2 Optical Switch
(09/01/2004)
In this paper, time division multiplexing with optical switches in a multi-sensor system for level measurements with POF is reported. POF are used in the sensor heads and as transmission media along the optical network. ...

Lamb wave detection with a fiber optic angular displacement sensor
(Spie-int Soc Optical Engineering, 2015-01-01)
In this work we show that the fiber optic angular displacement sensor is capable of Lamb wave detection, with results comparable to a piezoelectric transducer. Therefore, the fiber optic sensor has a great potential to be ...
Optical chemical sensors using polythiophene derivatives as active layer for detection of volatile organic compounds
(ELSEVIER SCIENCE SALAUSANNE, 2012)
Several studies on polythiophene gas sensors, based mainly on electrochemical and gravimetric principles can be found in the literature. However, other principles of gas detection, such as optical and thermal, are still ...
