SIMToolbox: a MATLAB toolbox for structured illumination fluorescence microscopy

Tomas Lukes

SIMToolbox is an open-source, modular set of functions for MATLAB equipped with a user-friendly graphical interface and designed for processing two-dimensional and three-dimensional data acquired by structured illumination microscopy (SIM). Both optical se ...

System for optical detection and imaging of sub-diffraction-limited nano-objects

Martinus Adela Maria Gijs, Matteo Cornaglia, Hui Yang

Nano-objects (8) with feature size smaller than the classical Abbe's diffraction limit can be optically detected via a microlens (4) array configured in a miniaturized microfluidic device. A hydrophilic microwell (3) array in a hydrophobic layer (2) is fir ...

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 ...

Digital confocal microscopy through a multimode fiber

Demetri Psaltis, Christophe Moser, Damien Claude-Marie Loterie, Salma Farahi, Alexandre Goy, Ioannis Papadopoulos

Acquiring high-contrast optical images deep inside biological tissues is still a challenging problem. Confocal microscopy is an important tool for biomedical imaging since it improves image quality by rejecting background signals. However, it suffers from ...

On-chip near-infrared optical spectrometer based on single-mode Epo waveguide and gold nanoantennas

Toralf Scharf, Irène Antoinette Philipoussis, Joab Di Francesco

We report about optical spectrometry using gold nanostructures printed on top of an integrated optical waveguide. The optical waveguide is a single-mode buried waveguide made from a combination of photo-polymerizable materials and is fabricated by photolit ...

Confocal polarization imaging in high-numerical-aperture space

Carlos Alberto Macias Romero

In this work we describe theoretical and experimental physical aspects of high-resolution imaging polarimetry and its application to polarization-multiplexed encoding. We theoretically demonstrate that it is possible to resolve the orientation of two fixed ...

Real-time 3D particle manipulation visualized using volume holographic gratings

Yves Chevallier

Holographic optical tweezers (HOTs) extend optical trapping into three dimensions. Volume imaging then becomes a concern as trapped objects are easily moved out of focus of the imaging objective lens. Here we demonstrate a three-dimensional real-time inter ...
