Abstract

U ovom radu dan je pregled optičkih senzorskih sustava temeljenih na svjetlovodnoj rešetci. Opisana su svojstva svjetlovodnih rešetki. Obrađene su metode detektiranja pomaka valne duljine, te su opisane metode multipleksiranja više svjetlovodnih rešetki u jednom svjetlovodu. Obrađena je konvolucijska metoda detekcije Braggove valne duljine uz prisustvo šuma. Eksperimentalno izveden optički sustav za mjerenje temperature.

Abstract (english)

In this diploma thesis rewiw of optical sensors based on fiber graing is given. Fiber Bragg gratings are described. Also, methods used to detect the wavelength shift and methods of multiplexing multiple fiber sensors into a single fibre are described. Convolution method for detecting the Bragg wavelength with noice presence is shown. Optical sensor system based on fiber gratings for measuring temperature is experimentally designed.
