Remote fiber optic polarization sensors in special environments
Baláž, Dominik ; Slavíček, Karel (referee) ; Grenar, David (advisor)
The aim of this thesis is to analyze the propagation of light in optical fibers using two polarization planes and to assess current polarization sensors. Emphasis is placed on the remote powering of polarization sensors in special environments. The main contribution of this work is the design of the functional arrangement of the optical fiber components to enable efficient use of the sensors in special environments, with emphasis on the detection of changes in non-electrical quantities. The results of the work confirm that the sensors provide a high degree of reliability in harsh environments and so are ideal for application in special environments, being suitable for detection over longer distances along with the possibility of use in military and chemical environments.

Multi-channel polarization optical fiber sensors in wave multiplex technique
Švehlík, Martin ; Grenar, David (referee) ; Filka, Miloslav (advisor)
The diploma thesis deals with the optical fiber sensor system assembly and its possibilities using 100 GHz wavelength multiplexing (DWDM), when using standard single-mode communication fibers. In the introduction, the necessary theoretical knowledge is discussed. The aim of the work is to design a temperature field violation sensor with remote excitation and detection. The practical part of the thesis contains the design and assembly of the measuring workplace. Also, the results of each measurement are presented, and at the end, they are compared and assessed.
