The optical displacement sensor was selected for accurate length measurement. aim of this article is to determine the mathematical measurement model using an assembled measuring chain by calibration. uncertainty balance determined in next part article.

Incorporation of planar waveguide technology into a spectroelectrochemical sensor is described. In this sensor design, a potassium ion-exchanged BK7 glass waveguide was over-coated with a thin film of indium tin oxide (ITO) that served as an optically transparent electrode. A chemically selective film was spin-coated on top of the ITO film. The sensor supported five optical modes at 442 nm and ...

The study focuses on the thermal and temperature sensitivity behavior of an optical fiber sensor device. In this article, a titanium nitride (TiN)-coated fiber Bragg grating (FBG) sensor fabricated using an ion beam sputtering system was investigated. The reflection spectra of the FBG sensor were tested using R-soft optical software to simulate the refractive index sensitivity. In these experim...

Since 1962 when Clark introduced the enzyme electrode, research has been intense for a robust implantable glucose sensor. An alternative "optical affinity sensor" was introduced by Jerome Schultz in 1979. The evolution of this sensor technology into a new methodology is reviewed. The approach integrates a variety of disparate concepts: the selectivity of immunoassays-selectivity for glucose was...

For the quick development of wireless sensor network and more attention for marine cause from every country, study of the application of network technology in subaqueous sensor system has been the hot topic. The subaqueous sensors network is mainly made up of a great number of sensor nodes and few workstations. These nodes can obtain important information such as the salinity, water temperature...

Abstract: This paper presents a highly sensitive fiber-optic oxygen sensor. The sensor was fabricated using palladium (II) meso-tetrakis (pentafluorophenyl) porphyrin (PdTFPP) and porous silica nanoparticles embedded in a tetraethylorthosilane (TEOS)/n-octyl-triethoxysilane (Octyl-triEOS) composite xerogel present as a coating on the end of the fiber. Sensitivity is quantified in terms of the r...

Distributed stress sensor with a scanning Michelson white light interferometer can be used to detect stress distribution and its value by analyzing polarization mode coupling caused by stress field in PMFs (polarization maintaining fibers). In the measurement of polarization coupling, the birefringence in sensing fiber is usually considered to be wavelength-independent. The spatial resolution o...
