Vliv uchycení optického vlákna s Braggovskou mřížkou na chování magnetostrikčních materiálů

Abstract

The subject of this bachelor thesis is the study of the influence of optical fibers with Bragg grating on behaviour of magnetostrictive materials. The theoretical part of the bachelor thesis is devoted to clarification and description of basic concepts - magnetostrictive phenomenon and magnetostrictive materials. The following chapter deals with the principles that Bragg grating reflects light at a certain wavelength. This chapter also contains a description of this phenomenon. The practical part is focused on attaching the Bragg grating to the magnetostrictive material. Subsequently, measurements of the reflected wavelengths of the light, the description of the measurement and the measuring instruments will be carried out and, of course, the results will be evaluated.
