Měření teploty okolí pomocí braggovských vláknově optických mřížek

Abstract

The diploma thesis is focused on the fiber optical Bragg gratings. Single mode optical fibers, which are used in manufacturing Bragg gratings, are described in first part. In following part, there is short summary of lasers, which are employed with measuring practical part of this labor. In next chapter there is described short principle of operation fiber Bragg gratings and several distinct types of fiber Bragg grating structures. In following past there is principle of operation of instrument WA-7100/7600, which was also used for measuring. In last and practical part of this labor is described measuring of spectral characteristics Bragg gratings and interpretation attained results.
