Fiber Optic Sensors for Detection of Toxic and Biological Threats
Protection of public and military personnel from chemical and biological warfareagents is an urgent and growing national security need. Along with this idea, we havedeveloped a novel class of fiber optic chemical sensors, for detection of toxic and biologicalmaterials. The design of these fiber optic sensors is based on a cladding modificationapproach. The original passive cladding of the fiber...
متن کاملFiber-Optic Sensors for Explosives Detection
As one of the most enduring hot topics, explosives detection commands world-wide interest among scientists across universities and research institutes. Abundant research achievements pertaining to this subject have been r eported. Various choices of commercial and military-grade detection units are available for deployment. Yet, airport security and the continuing threat of improvised explosive...
متن کاملDistributed Fiber-Optic Sensors for Vibration Detection
Distributed fiber-optic vibration sensors receive extensive investigation and play a significant role in the sensor panorama. Optical parameters such as light intensity, phase, polarization state, or light frequency will change when external vibration is applied on the sensing fiber. In this paper, various technologies of distributed fiber-optic vibration sensing are reviewed, from interferomet...
متن کاملFiber-Optic Chemical Sensors and Fiber-Optic Bio-Sensors
This review summarizes principles and current stage of development of fiber-optic chemical sensors (FOCS) and biosensors (FOBS). Fiber optic sensor (FOS) systems use the ability of optical fibers (OF) to guide the light in the spectral range from ultraviolet (UV) (180 nm) up to middle infrared (IR) (10 μm) and modulation of guided light by the parameters of the surrounding environment of the OF...
متن کاملCOMPARISON OF DIFFERENT GLASS COMPOUNDS FOR INTRINSIC FIBER OPTIC TEMPERATURE SENSORS
Different glasses suitable for temperature sensing in the fiber optic sensors were studied in this article. The phase changes for eight different glass materials were calculated and results were compared. Our results showed that extra dense flint glass is the most sensitive one, while pure silica results in the lowest phase change. In another study the effect of wavelength on the phase variatio...
