Leakage of information through existing fibre optic infrastructures inside buildings
Kyselova, Yuliia ; Dejdar, Petr (referee) ; Münster, Petr (advisor)
The bachelor thesis deals with the possibilities of detecting acoustic and mechanical vibrations through existing optical data infrastructures inside buildings. The work includes a description about optical fiber and a theoretical analysis of the possibilities of implementing data distribution inside buildings, it also includes an analysis of methods for implementing optical fiber microphones. In the practical part of the work, the measurement was performed with an optical fiber microphone and then using an interferometer and a sensor based on the polarization method.
