Iterative method for zero-order suppression in off-axis digital holography

Christian Depeursinge, Nicolas Pavillon

We propose a method to suppress the so-called zero-order term in a hologram, based on an iterative principle. During the hologram acquisition process, the encoded information includes the intensities of the two beams creating the interference pattern, whic ...

Cell refractive index tomography by digital holographic microscopy

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

For what we believe to be the first time, digital holographic microscopy is applied to perform optical diffraction tomography of a pollen grain. Transmission phase images with nanometric axial accuracy are numerically reconstructed from holograms acquired ...

Digital holographic microscopy for study cellular dynamics

Pierre Magistretti, Pierre Marquet, Christian Depeursinge, Benjamin Rappaz, Etienne Cuche

Based on an original numerical reconstruction algorithm (E. Cuche et al. Appl. Opt. 38, 6994 1999), we have developed a Digital Holographic Microscope (DHM), in a transmission mode, allowing to investigate noninvasively cellular structures and dynamics. DH ...

WAVE FRONT SENSING METHOD AND APPARATUS

Pierre Marquet, Christian Depeursinge, Tristan Colomb, Etienne Cuche, Florian Charrière, Nicolas Aspert, Frédéric Montfort, Stéphane Bourquin, Mihaela Marian

A new way of mixing instrumental and digital means is described for the general field of wave front sensing. The present invention describes the use, the definition and the utility of digital operators, called digital wave front operators (DWFO) or ... A n ...
