Structured light generation by refractive-diffractive micro optical array illuminators

Maryam Yousefi

Structured light generation having broad applications in different optical fields, is the topic of this thesis. Our structured light generation strategy is based on applying periodic microoptical elements at the refraction-diffraction limit, under a focuse ...

La phénoménotechnique questionnée par la médiation. L'exemple du showroom du Larsim

Yohann Michel Franck Guffroy

The purpose of this article is to present a space of mediation developed by the astrophysicist Vincent Minier and the philosopher Vincent Bontems at the Commissariat à l’Énergie atomique et aux Énergies renouvelables. This room, called “showroom”, promotes ...

Turning a normal microscope into a super-resolution instrument using a scanning microlens array

Martinus Adela Maria Gijs, Gergely Huszka

We report dielectric microsphere array-based optical super-resolution microscopy. A dielectric microsphere that is placed on a sample is known to generate a virtual image with resolution better than the optical diffraction limit. However, a limitation of s ...

Determination of sub-diffraction-limited organelles and biomolecules using microsphere lenses in combination with fluorescence microscopy

Martinus Adela Maria Gijs, Johan Auwerx, Hui Yang, Norman Lionel Moullan

We propose the use of a high-refractive index glass microsphere in combination with a conventional fluorescence microscope for imaging sub-cellular organelles and biomolecules. The microsphere is placed on a sample that is immersed in water, collects the n ...

Optical microscopy using a glass microsphere for metrology of sub-wavelength nanostructures

Martinus Adela Maria Gijs, Hui Yang

A technique that allows direct optical imaging of nanostructures and determines quantitatively geometric nanofeatures beyond the classical diffraction limit by using high-refractive index glass microspheres is introduced. The glass microsphere is put on a ...

A two-arm coordination model for phantom limb pain rehabilitation

Ronan Boulic, Eray Molla

Following limb loss, patients usually continue having sensations on their missing limbs as if they were still present. Signicant amount of such sensations are painful and referred as Phantom Limb Pain (PLP). Previous research has shown that providing the p ...

Method for Automatic Quality Control of Data in In-Vivo Images

Bénédicte Marie Maréchal

A method for quality control assessment in single time-point in-vivo imaging data related to imaging of objects, includes acquiring an in-vivo image of the object with imaging apparatus, defining a background image corresponding to an imaged air of the in- ...

Lensless high-resolution on-chip optofluidic microscopes for Caenorhabditis elegans and cell imaging

Demetri Psaltis

Low-cost and high-resolution on-chip microscopes are vital for reducing cost and improving efficiency for modern biomedicine and bioscience. Despite the needs, the conventional microscope design has proven difficult to miniaturize. Here, we report the impl ...

Surgical navigation system

Charles Baur

The invention relates to a surgical navigation system, comprising a microscope to which a 3D measuring apparatus is rigidly fixed, for localising objects within the field of operation. Markers are fixed to the objects the position of which is desirable to ...

Détecteur de tridents dans les émulsions photographiques nucléaires

The direct creation of an electron-positron pair by a high-energy charged particle manifests itself in a certain type of track configuration which is known as a 'trident'. A device for automatic scanning and detection of 'tridents' in nuclear emulsion is d ...
