Fiber optic assemblies consist of an optical fiber, a reinforcement strand for support, and fiber opticconnectors. While the copper wires mostly depend on electrical pulses to transmit data. Fiber optic assemblies systems rely on light pulse transmissions carried through the cable which delivers data at a quicker rate.
High sensitivity, low-cost fiber-optic anemometer have good resolutions and flow sensors. This also has the reflective-single mode and the multimode-single mode structure with no pressure drop. In air stream, inside a wind tunnel provides a reliable dynamic range from 4 to 10 m/s. Wavelength shifting sensitivity of 435.13 pm/(m/s) and resolution of 17.4 × 10−3 m/s. Output power intensity peak sensitivity of 2.62 dB/(m/s) on selected spectra peak.
Polyethanol glycol assisted gold nanodendrites (AuNDs) are synthesized by low-temperature sol-gel method. Uniform distribution of elements with smooth morphology is reported. Phenophthalein encapsulated AuNDs has refractive index 1.18 at 550 nm after. The Acidity of rainwater (pH 6) is determined by prepared sensor for validity purpose and practical applications. A fast response ~0.87 s, repeatability/reproducibility and linear response (R2 = 0.8912) are obtained at 440 nm.
Fabrication of fiber optic assemblies is done by theplasmonic sensor using ONLY chemical methods. Sensors utilize extraordinary transmission of light for signal transduction. Sensitivity of sensor is as high as in the case of sensors fabricated by sophisticated methods. Development of 3D printed flow cell is also underway. There is a successful determination of equilibrium dissociation binding constants (protein A/IgG).
In this process, a highly sensitive photocatalytic phenol optic-fiber sensor is developed. UV-vis-light-driven photocatalytic film for the detection of phenol is created. The working principle and sensitivity of proposed sensors are theoretically analyzed. Sensitivity, selectivity, pH immunity, and detection limit are checked. The proposed sensor shows high sensitivity and low detection limits.
Emergence and development of the LMR phenomenon as a fiber optic sensing platform are discussed. The concept and configuration of fiber optic LMR sensor with its performance parameters are briefed. Refractive index sensors utilizing various transparent semiconducting metal oxides and polymers supporting LMR are presented. Fiber-optic chemical and biosensors utilizing LMR principle are reviewed. Thepotential of LMR based bulk / nanostructured sensors are reviewed.
