Angular velocity measurement with fiber optic interferometer
Sodomka, Pavel ; Šedivá, Soňa (referee) ; Havránek, Zdeněk (advisor)
This bachelor thesis deals with the proposal and implementation of optic-fibre interferometer using the Sagnac phenomenon which measures the angular speed. In the theoretical part of this work, the possible interferometers are closer described and specified, base of wave interference, problems of the rotatory movement. The Sagnac phenomenon is explained and described here. Further the possible constructions of the optical-fibre interferometers for the measurement of the angular speed, including the described errors, which prevent the correct assembling and the implementation of the sensor. In the practical part of this work, the optical-fibre interferometer with the minimal balanced configuration. The individual optical and optical-fibre elements are selected and described to the given configuration, such as the source of radiation, polarizer, controller of polarization, divider, phase modulator, isolator, detector, optical fibre and optical-fibre coil. There is the specified and based problem which did not allow to successfully finish the assembled optical-fibre interferometer. In conclusion of this work there is the recommendation how to solve the caused problem.
