Refractive Index Tomography by Digital Holographic Microscopy

Christian Depeursinge, Tristan Colomb, Nicolas Pavillon, Pierre Marquet, Jonas Kühn

3D Refractive Index (RI) tomography appears as a challenging perspective in the observation of microscopic 3D objects, biological cells in particular. Recent developments in Digital Holographic Microscopy have permitted to achieve accurate RI 3D images. ...

Comparative study of human erythrocytes by digital holographic microscopy, confocal microscopy, and impedance volume analyzer

Pierre Magistretti, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet

Red blood cell (RBC) parameters such as morphology, volume, refractive index, and hemoglobin content are of great importance for diagnostic purposes. Existing approaches require complicated calibration procedures and robust cell perturbation. As a result, ...

Sub-cellular quantitative optical diffraction tomography with digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Pierre Marquet, Jonas Kühn, Florian Charrière

Digital holographic microscopy (DHM) is an interferometric technique, providing quantitative mapping of the phase shift induced by semi- transparent microscopic specimens, such as cells, with sub-wavelenght resolution along the optical axis. Thanks to actu ...

Numerical aberrations compensation and polarization imaging in digital holographic microscopy

Tristan Colomb

In this thesis, we describe a method for the numerical reconstruction of the complete wavefront properties from a single digital hologram: the amplitude, the phase and the polarization state. For this purpose, we present the principle of digital holographi ...

A New High-Resolution Processing Method for the Deconvolution of Optical Coherence Tomography Signals

Michaël Unser, Thierry Blu

We show the feasibility and the potential of a new signal processing algorithm for the high-resolution deconvolution of OCT signals. Our technique relies on the description of the measures in a parametric form, each set of four parameters describing the op ...

A method for polarisation imaging using digital holography

Christian Depeursinge, Tristan Colomb, Etienne Cuche

A numerical holographic method, which is able to determine the amplitude components of the Jones vector of a wavefront in addition to its phase and amplitude, is presented. Two reference waves, with orthogonal polarisations interfere with the transmitted o ...

Electrostrictive nonlinearity in optical fiber deduced from Brillouin gain measurements

Luc Thévenaz, Philippe Robert

The nonlinear refractive index has drawn considerable attention these past few years, because it may significantly perturbate long-range propagation of lightwaves in optical fibers. Two main origins to this nonlinearity have been identified: nonresonant el ...
