Journal ArticleDOI
Investigation of optical birefringence at ferroelectric domain wall in LiNbO3 by phase-shift polarimetry
Melania Paturzo,L. Aiello,F. Pignatiello,Pietro Ferraro,Paolo De Natale,Marella de Angelis,Sergio De Nicola +6 more
TL;DR: In this article, the authors investigated the optical birefringence near the wall between two opposite domains in a z-cut congruent LiNbO3 through a full-field polarimetric method.
Proceedings ArticleDOI
Volume holographic gratings: fabrication and characterization
G. Bianco,Maria Antonietta Ferrara,Fabio Borbone,Antonio Roviello,Vito Pagliarulo,Simonetta Grilli,Pietro Ferraro,V. Striano,Giuseppe Coppola +8 more
TL;DR: In this paper, a photopolymer sensitive to light at 532nm was used to record volume holographic grating and a flexible material is used to write Volume Holographic Gratings.
Journal ArticleDOI
Stain-free identification of cell nuclei using tomographic phase microscopy in flow cytometry
Daniel Pirone,Joowon Lim,Francesco Merola,Lisa Miccio,Martina Mugnano,Vittorio Bianco,Flora Cimmino,Feliciano Visconte,Anna Montella,Mario Capasso,Achille Iolascon,Pasquale Memmolo,Demetri Psaltis,Pietro Ferraro +13 more
TL;DR: In this paper , a method based on statistical inference was proposed to identify the cell nucleus using a refractive index tomogram of stain-free cells reconstructed through the tomographic phase microscopy in flow cytometry mode.
Journal ArticleDOI
Reflective grating interferometer in a noncollimated configuration
TL;DR: A third-order aberration analysis for a reflective grating interferometer (RGI) is developed for a noncollimated configuration that has the potential to be applied for isolating and measuring coma and a possible configuration for this application is proposed.
Journal ArticleDOI
Automatic Digital Hologram Denoising by Spatiotemporal Analysis of Pixel-Wise Statistics
Marco Leo,Cosimo Distante,Melania Paturzo,Pasquale Memmolo,Massimiliano Locatelli,E. Pugliese,Riccardo Meucci,Pietro Ferraro +7 more
TL;DR: The proposed approach to reduce the noise in a reconstructed hologram image not only takes into account spatial information but also temporal statistics associated with the pixels, which gives better both visual and quantitative results.
