Abstract:V magistrski nalogi je prikazana tehnologija izdelave miniaturnega vlakenskega tlačnega senzorja, ki je zaradi preprostih in malo številčnih procesnih korakov primerna za ceneno serijsko proizvodnjo. Tehnologija temelji na uporabi posebnega senzorskega vlakna, selektivnem jedkanju in mehansko-kemični obdelavi vrha optičnega vlakna. Celoten proizvodni proces je ob minimalnih nastavitvah in prilagoditvah parametrov izdelave primeren za izdelavo poljubno občutljivih tlačnih senzorjev. V sklopu naloge sta poleg tlačnega senzorja predstavljena še dva tipa miniaturnih kombiniranih tlačno-temperaturnih vlakenskih senzorjev, ki imata visoko tlačno občutljivost in široko temperaturno področje. V obeh primerih senzor predstavlja interferometer, ki je zgrajen iz dveh zaporednih Fabry-Perot resonatorjev. V prvem primeru je senzor izdelan na vrhu dovodnega enorodovnega vlakna. Zanj je narejen matematični model za izračun odbitega svetlobnega toka, ki potuje skozi dve oz. tri polprepustna zrcala. V drugem primeru je senzor izdelan na vrhu mnogorodovnega vlakna, ki senzorju omogoča cenovno ugodnejše signalno procesiranje in večjo robustnost.
Keywords:miniaturni vlakenski optični Fabry-Perot senzor, interferometer, dvo-parametrični senzorji, simultano merjenje tlaka in temperature, mikro-obdelava, polirna naprava, selektivno jedkanje, posebna optična vlakna

Title:Miniature pressure and temperature-pressure fiber-optic sensors
Abstract:In presented M.Sc. thesis the technology and design of miniature fiber-optic pressure sensor was demonstrated. The production process consists of few steps that are suitable for low cost serial production. The technology is based on use of a special custom made optical fiber, selective etching, and micromachining of an optical fiber end. The production process is appropriate for design of pressure sensors having arbitrary pressure sensitivities, achieved with minimal adaptation of production parameters. Furthermore, thesis presented two different types of dual parameter sensors for simultaneous measurements of pressure and temperature. Sensors demonstrate high pressure sensitivity and broad temperature range. In both cases, interferometric sensor consists of two Fabry-Perot resonators in series at optical lead-in fiber end. In the first case, the sensor is integrated into a standard lead-in single-mode fiber. Conditions in single mode sensors are in detail described with mathematical model. In the second case, the sensor is integrated into a standard lead-in multimode fiber that in contrast to single mode sensor presents the possibility for reduction of signal processing costs.
Keywords:Miniature fiber-optic Fabry-Perot sensor, interferometer, dual parameter optical sensors, measuring pressure and temperature simultaneously, micromachining, polishing device, selective etching, custom made optical fibers
