Journal ArticleDOI
A Mach–Zehnder interferometric system for measuring the refractive indices of uniaxial crystals
Sergio De Nicola,Pietro Ferraro,Andrea Finizio,Paolo De Natale,Simonetta Grilli,Giovanni Pierattini +5 more
TL;DR: In this article, a new interferometric technique for measuring the ordinary and extraordinary refractive indices of uniaxial crystals was proposed based on the measurement of the rotation-dependent phase changes of the optical path length in crystal plates.
Journal ArticleDOI
Digital holographic microscopy for the evaluation of human sperm structure.
Giuseppe Coppola,G. Di Caprio,Martin Wilding,Pietro Ferraro,G. Esposito,L. Di Matteo,Roberta Dale,Brian Dale +7 more
TL;DR: It is shown that DHM generates useful information on the dimensions and structure of human sperm, not revealed by conventional phase-contrast microscopy, in particular the volume of vacuoles, and suggested its use as an additional prognostic tool in assisted reproduction technology.
Journal ArticleDOI
Digital holography microscope as tool for microelectromechanical systems characterization and design
Giuseppe Coppola,M. Iodice,Andrea Finizio,S. De Nicola,Giovanni Pierattini,Pietro Ferraro,Carlo Magro,G. E. Spoto +7 more
TL;DR: The high sensitivity of the proposed method enables us to precisely determine the structure morphology and calculate the intrinsic stress and bending moment, in good agreement with an analytical model, and can be exploited to assess the fabrication process and the functionality as well as the reliability of micromachined structures.
Proceedings ArticleDOI
Characterization of MEMS structures by microscopic digital holography
Giuseppe Coppola,Sergio De Nicola,Pietro Ferraro,Andrea Finizio,Simonetta Grilli,Mario Iodice,Carlo Magro,Giovanni Pierattini +7 more
TL;DR: In this article, the use of digital holography (DH) as a metrological tool for inspection and characterization of MEMS structures was proposed, which can be efficiently employed to assess the fabrication process of micro structures as well as to test their behaviour in operative conditions.
Journal ArticleDOI
Mid-infrared digital holography and holographic interferometry with a tunable quantum cascade laser
Marco Ravaro,Massimiliano Locatelli,E. Pugliese,I. Di Leo,M. Siciliani de Cumis,Francesco D'Amato,Pasquale Poggi,Luigi Consolino,Riccardo Meucci,Pietro Ferraro,P. De Natale +10 more
TL;DR: This work demonstrates a similar and more compact holographic system based on an external cavity quantum cascade laser emitting at 8 μm, which allows the acquisition of speckle holograms of scattering objects, which can be processed in real time.
