UniSa - IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishMechanical vibrations in the frame of an interferometer can introduce a space-dependent factor throughout an interferogram, making its analysis quite difficult. This factor is formally equivalent to the modulus of the complex degree of coherence in the case of quasimonochromatic light. A simple method for retrieving the underlying phase distribution and detecting small perturbations is presented. Introducing an appropriate correction for the above-mentioned factor, good sensitivity is also achievable in noisy environments.

| Abstract: | Mechanical vibrations in the frame of an interferometer can introduce a space-dependent factor throughout an interferogram, making its analysis quite difficult. This factor is formally equivalent to the modulus of the complex degree of coherence in the case of quasimonochromatic light. A simple method for retrieving the underlying phase distribution and detecting small perturbations is presented. Introducing an appropriate correction for the above-mentioned factor, good sensitivity is also achievable in noisy environments. |
