Living specimen tomography by digital holographic microscopy: morphometry of testate amoeba

Christian Depeursinge, Tristan Colomb, Nicolas Pavillon, Benjamin Rappaz, Pierre Marquet, Edward Mitchell, Florian Charrière, Thierry Jean Heger

This paper presents an optical diffraction tomography technique based on digital holographic microscopy. Quantitative 2-dimensional phase images are acquired for regularly-spaced angular positions of the specimen covering a total angle of π, allowing to bu ...

Fluorescence correlation spectroscopy

Ramachandra Rao

Fluorescence Correlation Spectroscopy (FCS) has become an important tool for measuring diffusion, concentration and molecular interactions in biomolecular systems. Two major requirements for FCS are good collection efficiency and a small and well defined e ...

Single molecule detection and fluorescence correlation spectroscopy on surfaces

Kai Hassler

In this thesis a new approach for single molecule detection and analysis is explored. This approach is based on the combination of two well established methods, fluorescence correlation spectroscopy (FCS) and total internal reflection fluorescence microsco ...

Multiple optical trapping in high gradient interference fringes

René Salathé, Fabrice Merenda, Johann Rohner, Jean-Marc Fournier

In biological investigations, many protocols using optical trapping call for the possibility to trap a large number of particles simultaneously. Interference fringes provide a solution for massively parallel micro-manipulation of mesoscopic objects. Concur ...

Extension of the Williams-Clapper model to stacked nondiffusing colored coatings with different refractive indices

Roger Hersch, Mathieu Hébert

We propose a model for predicting the reflectance and transmittance of multiple stacked nonscattering coloring layers that have different refractive indices. The model relies on the modeling of the reflectance and transmittance of a bounded coloring layer, ...

Solid immersion lens used in a microscope with a lens system is made of a material having a refractive index that is selected so that the numerical aperture of the lens system

Theo Lasser, Ramachandra Rao

The invention relates to a solid immersion lens (SIL) for a microscope, comprising a lens system with a predetermined numerical aperture. The refractive index of the material of the solid immersion lens is selected in such a way that the numerical aperture ...

Microlenses metrology with digital holographic microscopy

Christian Depeursinge, Tristan Colomb, Etienne Cuche, Frédéric Montfort, Jonas Kühn, Florian Charrière

Digital holographic Microscopy (DHM) is an imaging modality reconstructing the wavefront in a numerical form, directly from a single digitalized hologram. It brings quantitative data derived simultaneously from the amplitude and phase of the complex recons ...

Polarization control and sensing with two-dimensional coupled photonic crystal microcavity arrays

Hatice Altug

We have experimentally studied polarization properties of the two-dimensional coupled photonic crystal microcavity arrays and observed a strong polarization dependence of the transmission and reflection of light from the structures-effects that can be empl ...
