Journal ArticleDOI
Compensation of the inherent wave front curvature in digital holographic coherent microscopy for quantitative phase-contrast imaging
Pietro Ferraro,Sergio De Nicola,Andrea Finizio,Giuseppe Coppola,Simonetta Grilli,Carlo Magro,Giovanni Pierattini +6 more
TL;DR: An approach is proposed for removing the wavefront curvature introduced by the microscope imaging objective in digital holography, which otherwise hinders the phase contrast imaging at reconstruction planes and it is shown that a correction effect can be obtained at all reconstruction planes.
Journal ArticleDOI
Whole optical wavefields reconstruction by digital holography.
Simonetta Grilli,Pietro Ferraro,S. De Nicola,Andrea Finizio,Giovanni Pierattini,Riccardo Meucci +5 more
TL;DR: It is shown that this technique can be efficiently used for obtaining quantitative information from the intensity and the phase distributions of the reconstructed field at different locations along the propagation direction.
Journal ArticleDOI
Extended focused image in microscopy by digital Holography.
Pietro Ferraro,Simonetta Grilli,Domenico Alfieri,Sergio De Nicola,Andrea Finizio,Giovanni Pierattini,Bahram Javidi,Giuseppe Coppola,V. Striano +8 more
TL;DR: It is demonstrated that an extended focused image of an object can be obtained through digital holography without any mechanical scanning or special optical components.
Journal ArticleDOI
Controlling image size as a function of distance and wavelength in Fresnel-transform reconstruction of digital holograms
Pietro Ferraro,Sergio De Nicola,Giuseppe Coppola,Andrea Finizio,Domenico Alfieri,Giovanni Pierattini +5 more
TL;DR: A method for controlling the size of amplitude and phase images reconstructed from digital holograms by the Fresnel-transform method is proposed and demonstrated and solves the problem of superimposition in multiwavelength digital holography for color display and holographic interferometry applications.
Journal ArticleDOI
Digital holographic microscope with automatic focus tracking by detecting sample displacement in real time
TL;DR: A new method for focus tracking during the recording of a sequence of digital holograms while the sample experiences axial displacement is proposed and can be applied as a quasi-real-time procedure.
