Fiber optic strain sensors, specifically designed for high temperature environments, were used to monitor strain on stainless steel specimens at elevated temperatures up to 2460°F (1349°C). The fatigue loading test results presented here were conducted by the Fiber and Electro-Optics Research ...
20.4.2 Optical fiber sensors An optical fiber sensor is essentially an optical fiber (core) surrounded by a cladding with a lower refractive index. Light travels through the core with little energy loss, because of the total reflection of the light inside the core (Fig. 20.15). External stimu...
It is presented the fabrication and characterization of optical fiber sensors for refractive index measurement based on localized surface plasmon resonance (LSPR) with gold nano-islands obtained by single and by repeated thermal dewetting of gold thin films. Thin films of gold deposited on silica (Si...
The article proposes a localized surface plasmon resonance (LSPR) sensor based on dual-tapered optical fiber (DTOF) that can detect cholesterol concentrations in the human body. To excite the LSPR effect and improve the sensing probe's sensitivity, gold nanoparticles (AuNPs) were immobilized on ...
To develop the sensor, a tapered single-mode optical fiber has been used with the well-known phenomenon of localized surface plasmon resonance (LSPR). For LSPR, the tapered region is immobilized with synthesized gold nanoparticles (AuNPs) and zinc oxide nanoparticles (ZnO-NPs) whose absorbance ...
