This work searches to develop and to optimize a holographic interferometer that it uses the photorefractive Bi12SiO20 (BSO) crystals in diffusive regimen with configuration exhibiting diffraction anisotropy for RealTime Holographic Interferometry (RTHI) and applications in surfaces analysis. In RTHI with photorefractive BSO crystals, the writing-reading hologram process is made in real-time in ...

Optical holographic interferometry was used to study standing sound waves in air inside a resonance tube driven by a small loudspeaker at one end. The front face of the resonance tube was constructed of plexiglass, allowing optical interrogation of the tube interior. The object beam of the holographic setup was directed through the plexiglass and reflected off the back wall of the resonator. Wh...

Permanent Scatterer Interferometry (PSI) has been used to detect and characterize the subsidence of the Pisa urban area, which extends for 33 km2 within the Arno coastal plain (Tuscany, Italy). Two SAR (Synthetic Aperture Radar) datasets, covering the time period from 1992 to 2010, were used to quantify the ground subsidence and its temporal evolution. A geotechnical borehole database was also ...
