Abstract:Uporaba optičnih vlakenskih senzorjev rotacij/zasukov se je pokazala kot robustna in učinkovita tehnologija na področju nadzora v panogah, kjer je pomembno aktivno spremljanje rotacij/zasukov (geofizika, navigacija, letalska industrija, vojaška industrija ipd.). Močnejši preboj na druga področja pa največkrat omejuje konfiguracija senzorja, kjer so dosedanje rešitve zgrajene z uporabo posebnih vlaken v linijski konfiguraciji, pri kateri je potreben dostop do senzorja tako s strani svetlobnega vira, tj. vhodnega dela optičnega vlakna, kot s strani detektorskega dela. Takšna konfiguracija lahko omeji področja uporabe senzorja v aplikacijah, kjer so zahteve po kompaktnosti in majhnih dimenzijah bistvenega pomena. Sicer obstajajo rešitve, ki ne zahtevajo linijske postavitve, kot so sistemi na osnovi Braggovih sit, pa vendar, tako kot pri sistemih v linijski konfiguraciji, temeljijo takšne rešitve na kompleksnih metodah za signalno razločanje z visoko ločljivostjo, kar jih naredi neprivlačne za praktično uporabo. Veliko takšnih sistemov izkazuje tudi temperaturno odvisnost. V doktorski disertaciji smo se posvetili raziskavam optičnih vlakenskih senzorjev za meritve na področju rotacij/zasukov, s pomočjo katerih bi snovali sisteme v konfiguraciji z enojnim dovodnim vlaknom, ki so grajeni iz majhnega števila optičnih komponent, imajo preprosto konfiguracijo, omogočajo enostavno signalno razločanje merilnih vrednosti in so cenovno ugodni.

Title:Fiber optic sensors for point and quasi-distributed twist/rotation measurements, constructed on a single lead fiber : doctoral thesis
Abstract:Implementation of fiber optic twist/rotation sensors proved to be a robust and efficient technology in several industrial fields (geophysics, navigation, aeronautic and military industry) where active monitoring of twist/rotation parameters is essential. However, a greater breakthrough of this technology is restrained due to current fiber optic sensor twist/rotation solutions, employing different configurations of specialty fibers, which either depend on in-line configurations or a combination of specialized gratings. In-line configuration is often limiting in various applications, as it requires physical access to the measurement location from two opposite directions using two lead fibers. Limited fiber bend diameter thus limits the minimum size of the device to impractical dimensions in the cases of applications requiring small sizes or volumes. Sensing systems that depend on (specialized) gratings can be configured for operating in simpler and more compact back-reflection modes, however alike in-line configurations, they employ complex and cost-prohibitive signal interrogation methods which also experience limited temperature stability. Our focus in this dissertation was the research for new approaches in the area of fiber optic twist/rotation measurements to yield a single lead sensor configurations, which are built from a small quantity of optical components, have a straightforward design, which allow simple and cost-efficient signal interrogation methods.
Keywords:optical fibers, sensors, polarimetric sensors, quasi-distributed sensors, distribute measurements, temperature compensation
