Abstract
U ovom diplomskom radu dan je pregled optičkih senzorskih sustava, objašnjen je princip rada svjetlovodnih Braggovih rešetki te njihova mogućnost implementacije u senzorske sustave, s naglaskom na sustave za mjerenje temperature. Svjetlovodne Braggove rešetke predstavljaju odlično rješenje za mjerenje temperature, zbog svoje visoke osjetljivosti na promjenu temperature koja se manifestira promjenom u Braggovoj valnoj duljini. Prednosti svjetlovodnih Braggovih rešetki su njihova visoka osjetljivost, linearnost, neovisnost o intenzitetu optičkog signala te mogućnost mjerenja u inače nedostupnim područjima. Napravljena je karakterizacija svjetlovoda s četiri Braggove rešetke te njihova kalibracija kako bi se na temelju izmjerenog pomaka u Braggovoj valnoj duljini mogla odrediti temperatura. Kalibriran je ugodivi laserski izvor koji koristi ugađanje valne duljine istosmjernim naponom. Realiziran je prijenosni senzorski sustav za mjerenje temperature koji se sastoji od uskopojasnog ugodivog laserskog izvora, cirkulatora, Braggovih svjetlovodnih rešetki, fotodetektora, mikrokontrolera i osobnog računala. Ostvareni sustav može se koristiti za mjerenje razdiobe temperature mora.
Abstract (english)
This master's thesis presents the utilization of optical sensor systems and explores the concept of fiber Bragg gratings, along with their integration in sensor systems for temperature measurements. Fiber Bragg gratings exhibit a remarkable suitability for temperature measurements owing to their high sensitivity towards temperature changes, as evidenced by variations in the Bragg wavelength. Notable advantages of fiber Bragg gratings include their high sensitivity, linear response, insensitivity to optical signal intensity, and their ability to facilitate sensing in otherwise inaccessible environments. In this study, an optical fiber containing four Bragg gratings was subjected to calibration to establish a correlation between wavelength variations and changes in temperature. Additionally, a tunable laser source, which employs wavelength tuning through the use of direct current (DC) voltage, was also calibrated. A portable sensor system was developed and evaluated, comprising a tunable laser source, a circulator, a fiber containing four Fiber Bragg gratings (FBGs), a photodetector, an Arduino Nano 33, and a personal computer. This sensor system demonstrated promising capabilities for measuring sea temperature distribution, thereby offering potential applications in that domain.
