Measurement of very small displacements with fiber-optic interferometer
Vybíral, Dominik ; Šedivá, Soňa (referee) ; Havránek, Zdeněk (advisor)
This master's thesis is focused on optical methods of measurement of very small dynamic displacements. Principles of interfermeters with picometer resolution including Fabry-Pérot interferometer are discussed and an integration using this interferometer was designed. Parasitic influencers of Fabry-Pérot interferometer were described as well as signal processing methods for interferometer's output signal. An interferometric meter for measurement of dynamic displacement was designed with frequency range of several kHz. These parameters are achieved under condition of photonic crystal layer placed on measured sample.

Measurement of water parameters with fiber optic sensors
Vybíral, Dominik ; Šedivá, Soňa (referee) ; Havránek, Zdeněk (advisor)
This bachelor's thesis is focused on measuring of concentration of dissolved oxygen in water, particularly on fiber optics sensors based on fluorescence quenching. An overwiev of fiber optics probes was written. An integration was designed using fiber optics probe FOXY-R, spectrometer USB4000, monochromatic light source LLS-470 and bifurcated optical fiber BIF 600. Measuring application was designed using LabVIEW.
