Journal ArticleDOI
Quantitative phase-contrast microscopy by a lateral shear approach to digital holographic image reconstruction.
TL;DR: It is demonstrated that it is possible to obtain quantitative optical phase measurement in microscopy by a new single-image-processing procedure combining the concept of lateral shear interferometry (LSI) within a digital holography microscope.
Journal ArticleDOI
Angular spectrum method with correction of anamorphism for numerical reconstruction of digital holograms on tilted planes
TL;DR: A new method for numerically reconstructing digital holograms on tilted planes based on the angular spectrum of plane waves is presented, which is especially useful for tomographic image reconstruction.
Journal ArticleDOI
Optical properties of waveguides written by a 26 MHz stretched cavity Ti:sapphire femtosecond oscillator
Roberto Osellame,N. Chiodo,V. Maselli,A Yin,Margherita Zavelani-Rossi,Giulio Cerullo,Paolo Laporta,L. Aiello,S. De Nicola,Pietro Ferraro,Andrea Finizio,Giovanni Pierattini +11 more
TL;DR: The fabrication, by a 26 MHz stretched-cavity femtosecond Ti:sapphire oscillator, of optical waveguides in different glass substrates, and their optical characterization demonstrate a strong dependence of the fabrication process on the glass matrix.
Journal ArticleDOI
Recovering correct phase information in multiwavelength digital holographic microscopy by compensation for chromatic aberrations.
S. De Nicola,Andrea Finizio,Giovanni Pierattini,Domenico Alfieri,Simonetta Grilli,Lucia Sansone,Pietro Ferraro +6 more
TL;DR: It is demonstrated experimentally that correct phase imaging without 2pi ambiguity is obtainable in digital holography by using a multiwavelength approach in the microscope configuration.
Journal ArticleDOI
Three-dimensional image fusion by use of multiwavelength digital holography.
Bahram Javidi,Pietro Ferraro,Seung-Hyun Hong,Sergio De Nicola,Andrea Finizio,Domenico Alfieri,Giovanni Pierattini +6 more
TL;DR: It is demonstrated experimentally that, through the image fusion technique with multiresolution wavelet decomposition, it is possible to increase the details and contrast of 3D reconstructed images obtained by multiwavelength digital holography.
