Sensitivity Enhancement of Fiber Optic Diesel Adulteration Detection Sensor Using Stripped Clad SBend Section
A novel geometry for enhancing the sensitivity of intensity modulated refractometric fiber optic sensor for detection of adulteration level in diesel by kerosene is proposed. In this multimode plastic optical fiber is uncladded for specific length and bent into S shape. This geometry is simulated and analyzed using Beam Propagation Method in Beam prop RSOFT software. When sensor is immersed in ...

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 کاملFabry-Perot Diaphragm Fiber Optic Sensor (DFOS) for Acoustic Detection
The diaphragm fiber optic sensor (DFOS) solely based on Fabry-Perot multiple beam interference has been designed and fabricated with Micro-electric mechanical system (MEMS) technology. The silicon diaphragm with an embossed center was designed with an interference gap width kept accurately. The DFOS is verified to be truly and purely of Fabry-Perot type via a critical test. Parallel testing of ...
