Elektronski sistem za merenje deformacija pri savijanju pomoću polimernog optičkog vlakna sa osetljivom zonom / Electronic system for measurement of deformations under bending by usingpolymer optical fiber with sensitive zone

Description

<p>U ovoj doktorskoj disertaciji je razvijen elektronski senzorski sistem za merenje deformacija pri savijanju pomoću polimernog optičkog vlakna sa osetljivom zonom. Opisana je metoda izrade fiber-optičkog senzora zakrivljenosti pomoću polimernog optičkog vlakna. Izvršena je simulacija ponašanja senzora i urađena je karakterizacija senzora. Ispitana je mogućnost primene elektronskog senzorskog sistema za detekciju savijanja i loma građevinskih struktura. Pomoću istog senzora je realizovan fiber-optički goniometar za merenje ugla savijanja ljudskog kolena koji karakterišu linearni odziv u opsegu uglova od -45&deg; do 25&deg;, rezolucija od 1&deg; i osetljivost od 20 mV/&deg;. U tezi je takođe data metoda eliminacije grešaka koje mogu nastati usled savijanja delova vlakna koji vode do i od osetljive zone.</p> / <p>In this thesis, an electronic system for measurement of bend-induced<br />deformations by using polymer optical fiber with sensitive zone is developed.<br />A method for fabrication of the fiber-optic curvature sensor by using polymer<br />optical fiber is described. The simulation and characterization of the sensor<br />behavior have been conducted. The possibility of application of the proposed<br />electronic system in structural health monitoring for bending and crack<br />detection of civil engineering structures is investigated. Also, a fiber-optic<br />goniometer for human joint movement monitoring characterized by a linear<br />response in the range from -45&deg; to 25&deg;, resolution of 1&deg;, and the sensitivity of<br />20 mV/&deg; is implemented. A method for the elimination of errors which may be<br />caused due to bending of lead-in and lead-out sections of the fiber (leading<br />to and from the sensitive zone) is also described.</p>
