Nonlinearity management in optics: Experiment, theory, and simulation

We conduct an experimental investigation of nonlinearity management in optics using femtosecond pulses and layered Kerr media consisting of glass and air. By examining the propagation properties over several diffraction lengths, we show that wave collapse ...

Nanometer focusing properties of Fresnel zone plates described by dynamical diffraction theory

Christian David

The x-ray focusing properties of linear Fresnel zone plates have been derived by solving the Helmholtz equation for the field propagating through the zones. We consider the imaging of a point object into the first diffraction order of a volume zone plate h ...

Multiple scattering in optical coherence tomography. I. Investigation and modeling

Theo Lasser, Boris Clément Karamata, Marcel Leutenegger, Stéphane Bourquin, Markus Laubscher

We present a new model of optical coherence tomography (OCT) taking into account multiple scattering. A theoretical analysis and experimental investigation reveals that in OCT, despite multiple scattering, the field backscattered from the sample is general ...

Coherent grazing exit x-ray scattering geometry for probing the structure of thin films

We demonstrate a diffraction geometry which provides strong sensitivity to the microstructure of thin films. While a coherent beam of X-rays is being reflected from the surface of the sample, measurements were made of the scattering of the exit beam below ...

Digital Holographic Microscopy applied to Metrology

Pierre Magistretti, Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Pierre Marquet, Jonas Kühn, Florian Charrière, Mihaela Marian

We report on a method called Digital Holographic Microscopy (DHM) for the numerical reconstruction of digital holograms taken with a microscope. It allows for simultaneous amplitude and quantitative phase contrast imaging. The reconstruction method compute ...

Point spread function models for digital holographic microscopy

Christian Depeursinge, Mihaela Marian

Few models, based on the diffraction theory, are proposed in order to evaluate the point spread function of different microscope objectives used in a digital holographic microscope. Because in holography the phase information is essential, a 3D amplitude p ...

Parallel single molecule detection with a fully integrated single-photon 2X2 CMOS detector array

Theo Lasser, Radivoje Popovic, Alexis Rochas

We present parallel single molecule detection (SMD) and fluorescence correlation spectroscopy (FCS) experiments with a fully integrated complementary metal oxide semiconductor (CMOS) single-photon 2 X 2 detector array. Multifocal excitation is achieved wit ...

Low-data simulation of diffractive optical elements based on the zones geometry

Hans Peter Herzig

Design and simulation of two-dimensional diffractive optical elements are often limited by the amount of data required to represent the element in the computer's memory. We present a technique based on a geometrical description of the element, which requir ...

Digital holography applied to microscopy

Pierre Magistretti, Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Pierre Marquet, Mihaela Marian

We report on new developments of a technique, called Digital Holographic Microscopy (DHM), for the numerical reconstruction of digital holograms taken in microscopy, which allows simultaneous amplitude and quantitative phase contrast imaging. The reconstru ...

3D imaging of surfaces and cells by numerical reconstruction of wavefronts in Digital Holography applied to transmission and reflection microscopy

Pierre Magistretti, Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Pierre Marquet, Mihaela Marian

We report on a numerical method for the reconstruction of wavefronts in Digital Holographic Microscopy (DHM). It yields simultaneous amplitude and quantitative phase contrast imaging by acquiring a single hologram. The reconstruction method computes the pr ...
