Bending and Stretching in a Narrow Ribbon of Nematic Polymer Networks

We study the spontaneous out-of-plane bending of a planar untwisted ribbon composed of nematic polymer networks activated by a change in temperature. Our theory accounts for both stretching and bending energies, which compete to establish equilibrium. We s ...

Simultaneous estimation of unwrapped phase and phase derivative from a closed fringe pattern

Pramod Rastogi, Rishikesh Dilip Kulkarni

We propose a new approach for the direct estimation of the unwrapped phase from a single closed fringe pattern. The fringe analysis is performed along a given row/column at a time by approximating the phase with a weighted linear combination of linearly in ...

Towards an incoherent off-axis digital holographic microscope

Christian Depeursinge, Frédéric Montfort

We propose and experimentally demonstrate a system in which off-axis digital holographic microscopy is realized using a broadband illumination source. Single-shot holographic measurements are enabled, while the coherence noise is removed thanks to the broa ...

Off-axis digital holographic camera for quantitative phase microscopy

Christian Depeursinge, Christophe Moser, Frédéric Montfort, Zahra Monemhaghdoust

We propose and experimentally demonstrate a digital holographic camera which can be attached to the camera port of a conventional microscope for obtaining digital holograms in a self-reference configuration, under short coherence illumination and in a sing ...

Portable advanced off-axis camera for quantitative phase microscopy

Christian Depeursinge

We propose and experimentally demonstrate a device in which common-path interferometry combined with off-axis holographic geometry is used to realize a digital holographic camera which can be attached to the camera port of a conventional transmission micro ...

Modelling oriented investigations of primary radiation damage in ultra high purity Fe and FeCr alloys

Anna Prokhodtseva

In the quest of the structural materials for the future fusion reactor, it has been shown that ferritic/martensitic (F/M) steels are very promising candidates, with a good radiation resistance in terms of damage accumulation in the microstructure relative ...

Young's Type Interference for Probing the Mode Symmetry in Photonic Structures

Laurent Balet, Massimo Gurioli

A revisited realization of the Young's double slit experiment is introduced to directly probe the photonic mode symmetry by photoluminescence experiments. We experimentally measure the far field angular emission pattern of quantum dots embedded in photonic ...

Quantum complementarity of microcavity polaritons

Vincenzo Savona

We present an experiment that probes polariton quantum correlations by exploiting quantum complementarity. Specifically, we find that polaritons in two distinct idler modes interfere if and only if they share the same signal mode so that "which-way" inform ...

Speckle-averaged resonant Rayleigh scattering from quantum-well excitons

Benoît Marie Joseph Deveaud, Vincenzo Savona

We have measured the ultrafast resonant Rayleigh scattering from quantum-well excitons using Fourier-transform spectral interferometry. The experiment simultaneously measures a statistically significant number of speckles with 100 fs temporal resolution. W ...
