Microsphere-based super-resolution scanning optical microscope

Martinus Gijs, Hui Yang, Gergely Huszka

High-refractive index dielectric microspheres positioned within the field of view of a microscope objective in a dielectric medium can focus the light into a so-called photonic nanojet. A sample placed in such nanojet can be imaged by the objective with su ...

Single particle maximum likelihood reconstruction from superresolution microscopy images

Suliana Manley, Julia Gunzenhäuser

Point localization superresolution microscopy enables fluorescently tagged molecules to be imaged beyond the optical diffraction limit, reaching single molecule localization precisions down to a few nanometers. For small objects whose sizes are few times t ...

Resolving 1 million sensing points in an optimized differential time-domain Brillouin sensor

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Alejandro Dominguez Lopez

A differential pulse-width pair (DPP) Brillouin distributed fiber sensor is implemented to achieve centimetric spatial resolution over distances of several kilometers. The presented scheme uses a scanning method in which the spectral separation between the ...

Single molecule fluorescence resonance energy transfer scanning near-field optical microscopy: potentials and challenges

Giovanni Dietler, Mounir Driss Mensi, Anton Smirnov, Kanat Dukenbayev, Ekaterina Rostova, Andrey Mikhaylov

A few years ago, single molecule Fluorescence Resonance Energy Transfer Scanning Near-Field Optical Microscope (FRET SNOM) images were demonstrated using CdSe semiconductor nanocrystal-dye molecules as donor-acceptor pairs. Corresponding experiments reveal ...

Royal Soc Chemistry2015

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 ...

Optical Soc Amer2014

Life sciences have a constantly growing need for novel methodological approaches suitable to investigate the intracellular environment with increased temporal and spatial resolutions. Recently, optical near-field probes, such as laser-irradiated pointed me ...

Near Field Optical Microscopy Imaging with a Free Electron Laser in the 1-10 Micron Spectral Range: Overview and Perspectives

Giorgio Margaritondo

The need to image objects on increasingly finer scales and spatially localized specific molecules can be met by the combination of infrared, visible and Raman spectroscopy with scanning near-field microscopy, giving rise to a powerful nanospectroscopic too ...
