CINECA 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.
EnglishBy exploiting a novel quantitative imaging technique based on Synthetic Optical Holography, we describe the dynamic behaviour of optical vortices in a speckle pattern generated by the interference of random scattered waves from the rough surface of a glass substrate. The system combines the advantages of digital holography and low-coherence interferometry to retrieve multiple holograms with sub-nanometric spectral resolution. The collection of multiple images of the complex scattered field allows to provide a statistical characterization of the phase singularities by changing the exciting wavelength.
