Návrh a realizace interogační jednotky pro Braggovské mřížkové senzory ve viditelném spektru

Abstract

This diploma thesis deals with the study of Bragg gratings and methods for the evaluation of fiber optic sensors with Bragg gratings and the subsequent development of an evaluation unit for sensors with Bragg gratings. In the first part, the thesis deals with the theoretical introduction to Bragg gratings, their fabrication, applications in sensor systems and evaluation methods. The next part of the thesis deals with the optical spectrometer, its components, parameters, defects and possible configurations. In the last part, the design and implementation of an evaluation unit for Bragg grating sensors using the wavelength-to-position conversion method is performed. Finally, the functionality of the evaluation unit is tested using the realized fiber optic Bragg grating sensor.
