This book was released on 2020-01-24 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, a distributed Brillouin sensor in perfluorinated polymer optical fibers utilizing BOFDA is presented. These commercially available polymer fibers offer beneficial characteristics for sensing applications such as higher break down strain up to 100 %, minimal bending radii below 2 mm, higher sensitivity to temperature and lower sensitivity to strain compared to their silica equivalent. The SBS parameters - backscattering power, linewidth and frequency shift - are inclusively related to the environmental parameters humidity, temperature and tensile strain. Furthermore, the perfluorinated polymer optical fibers are characterized with respect to the influence of relative humidity and temperature changes on spectral transmission absorption and Rayleigh backscattering, respectively. The chosen wavelength of operation at 1319 nm corresponds to lower fiber propagation loss (

Available in PDF, EPUB and Kindle. Book excerpt: Plastic Optical Fiber Sensors cover the fundamentals and applications of a new class of fiber sensors. With contributions from leading academics in the area, this book covers the theory of plastic optical fiber sensors or (POFs), as well as applications in oil, gas, biotechnology, and energy fields. Using multiple examples, the editors showcase the advantageous characteristics of POFs, such as ease of handling, large diameter, inexpensive peripheral components and simple termination tools. By doing so, the editors assert that there has been a proliferation of the use of POFs in new consumer products. The book also highlights uses for building various products, such as a POF sensor for oil trucker valve monitoring, a monitoring system for high voltage substation switch, an oil leaking sensor for offshore platforms and a solar tracker for illumination. Including over 300 black and white images, this book would be highly beneficial for professionals in manufacturing as well as academics in universities, particularly those who use optical fiber sensors on a regular basis.

Available in PDF, EPUB and Kindle. Book excerpt: Experimental and theoretical studies of the optical properties of large core step index (SI) plastic optical fibers (POF) and graded index (GI) POFs are reported. A set of criteria and analyses of physical parameters are developed in context to the major issues of POF applications in short-distance communication systems. Analyses are presented to show how the measured POF optical attenuation affects the overall performance in wavelength division multiplexing (WDM) and how use of perfluorinated polymers can overcome limitation inherent to current POF materials. Results of POF optical bandwidth measurements by direct picosecond time domain methods are reported and their relationship to refractive index profiles theoretically analyzed by the WKB and finite-element methods. Two high-resolution optical techniques of refracted near-field and transverse interferometric methods are presented and used to measure the index profiles of large core POFs. Results reveal that the index profile of current GI POF is not parabolic, but consists of two markedly different regions. Analysis of the index profile reveals that strong mode coupling increases the GI POF bandwidth from its profile-determined value of 0.43 GHz to its measured value of 3.0 GHz for 100m. We further study mode coupling effect inside POFs through various experimental techniques, including pulse broadening-length dependence measurements and far-field radiation pattern measurements.
