A new technique is presented, dynamic phase-shifting, which is based on a dedicated phase-shifting algorithm and a wavelet-transform analysis. This technique allows to perform measurements on non-static objects, using whole-field optical methods. These met ...
Fourier domain optical coherence tomography (FDOCT) is a high speed imaging technique with high axial resolution in the micro-meter-scale range combined with a high sensitivity allowing to probe 3D volumes of weakly back- scattering biological tissues in-v ...

Phase of the interference fringe pattern is known to convey important information in optical metrology. Typically, phase measurement using temporal techniques involves incorporating a piezoelectric device (PZT) in one arm of the interferometer for shifting ...
The thermotropic phase diagram of 1:1 co-crystals of hexamethylenetetramine and pimelic acid (heptanedioic acid) is investigated. Three crystalline phases are identified at ambient pressure. Phase I is disordered, as revealed by diffuse rods in its diffrac ...
The piezoelectric properties of the bismuth titanate niobate Bi7Ti4NbO21 have been studied. The two phase transitions at 677 degrees and 856 degrees C are analyzed based on the measured piezoelectric properties. It is shown that the Bi7Ti4NbO21 compound is ...

The domain nucleation and growth during polarization switching in Pb(Zr,Ti)O-3 (PZT) ferroelectric thin film capacitors with Pt top (TE) and bottom electrodes (BE) were studied by means of atomic force microscopy (AFM). The experimental configuration used ...
