چکیده
An electro-mechanical mathematical model of the functioning an optical fiber resonance piezoelectroluminescent (RPEL) sensor with external nonlinear elastic buffer layer has been developed. The is designed to measure distribution spectrum along length dynamic and/or static pressure using a resonant diagnostic method based on results measuring amplitude intensity resulting light flux at output from sensor. numerical values frequency characteristics (- these are proportionality coefficients for informative relationship "pressure/resonance frequency") RPEL sensor, which used in algorithm finding spectrum, different (first six) modes vibration, determined.

متن کاملA 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 کاملModeling Simulation and Fabrication of Fiber Optic Pressure Sensor Probe
Elastic element mechanical pressure gages consisting diaphragm are basically used for the differential pressure measurement. In FODPS, diaphragm acts as a reflector. A flexible disc of plastic is used as a diaphragm to convert the measuring pressure to the deflection of diaphragm. Concentric corrugations are designed to linearise the deflections according to pressure. Reference and measuring pr...

متن کاملFiber Optic Surface Plasmon Resonance based Refractive Index Sensor
In the present study, a surface plasmon resonance (SPR) based fiber optic sensor is proposed. The extreme sensitivity of SPR modes on the surrounding refractive index has been exploited to make the sensor. The optical fiber is coated with gold film which supports the propagation of surface plasmons. The SPR dip in the transmission spectrum is observed and its shift with varying refractive indic...
