Abstract
Tato bakalářská práce se zabývá interferometrií nedifrakčních svazků. V první části práce je uvedena teorie interference a teorie nedifrakčních svazků. Práce se zaměřuje na besselovy svazky generované pomocí axikonu. V druhé části práce jsou popsány provedené experimenty. Byly realizovány interference dvou klasických difrakčních svazků, dvou nedifrakčních svazků a interference difrakčního svazku s nedifrakčním. Byly použity dva interferometry: Michelsonův a Mach-Zehnderův. Interferenční obrazce byly zaznamenány pomocí CCD kamery a diskutovány. Výsledky byly podloženy simulacemi. Ukázalo se, že interference dvou nedifrakčních svazků poskytuje více informací ve srovnání s klasickou interferometrií gaussovských svazků. Pomocí interference difrakčního svazku s nedifrakčním lze vytvořit vírová pole. Měření interferenčních polí nedifrakčních svazků přineslo zajímavé výsledky, které otevírají nové možnosti pro výzkum i aplikace.
This bachelor thesis deals with interferometry of non-diffractive beams. In the first part of this thesis the theory of interference and the theory of non-diffractive beams are described. The work is focused on Bessel beams generated with an axicon. In the second part of this thesis experiments are described. Interference of two diffractive beams, of two non-diffractive beams and of diffractive with non-diffractive beam were experimentally realized. Michelson interferometer and Mach-Zehnder interferometer were used. Interference patterns were registered with CCD detector and were discussed. The results were supported by simulations. It has been shown that interference of two non-diffractive beams can provide more information in comparison with the classical interference of two Gaussian beam. Using interference of diffractive beam with nondiffractive can create vortex beam. Measurements of interference non-diffractive beams bring interesting results, which open new possibilities for research and applications.
