Proceedings ArticleDOI
Direct fabrication of polymer micro-lens array
Sara Coppola,Vito Pagliarulo,V. Vespini,Giuseppe Nasti,Federico Olivieri,Simonetta Grilli,Pietro Ferraro +6 more
TL;DR: In this article, a flexible pyroelectric-electrohydrodynamic (EHD) inkjet printer is presented, capable of manipulating highly viscous polymers, usable for optical integrated devices.
Journal ArticleDOI
Interferometric analysis of reorientational nonlinear phenomena at 10.6 μm in a nematic liquid crystal
Enrico Allaria,Stefano Brugioni,Sergio De Nicola,Pietro Ferraro,Simonetta Grilli,Riccardo Meucci +5 more
TL;DR: It is shown that accurate determination of the nonlinear refractive index can be obtained by analyzing the two-dimensional phase distribution of the modulated ring pattern and by comparison with the theoretical ring-pattern intensity distribution.
Book ChapterDOI
Digital holographic microscope for dynamic characterization of a micromechanical shunt switch
V. Striano,Giuseppe Coppola,Pietro Ferraro,Domenico Alfieri,Sergio De Nicola,Andrea Finizio,Giovanni Pierattini,Romolo Marcelli +7 more
TL;DR: In this paper, an asymmetric behavior of a dynamic MEMS was found due to impurities presence in the air gap between the bride and the substrate, and the DH analysis showed that it can have a very important role in the future process of dynamic MEMs characterization.
Proceedings ArticleDOI
New high compression method for digital hologram recorded in microscope configuration
TL;DR: It is demonstrated that the proposed sparse representation gives the possibility to obtain high compression factor with minimal loss in the quality of the reconstructed image.
Journal ArticleDOI
Impact Damage Investigation on Glass Fiber-Reinforced Plate Laminates at Room and Lower Temperatures through Ultrasound Testing and Electronic Speckle Pattern Interferometry
TL;DR: In this article, the impact area due to low-velocity impact tests at different impact energy values and different temperatures on glass fiber-reinforced plate laminates was investigated by two nondestructive evaluation (NDE) techniques, electronic speckle pattern interferometry (ESPI) and ultrasound testing (UT).
