Super-resolution optical imaging: A comparison

Overcoming the classical diffraction limit in optical microscopy is known to be achievable by a variety of far-field and near-field microscopy techniques. More recently, so-called micro-object-based optical super-resolution microscopy techniques have emerg ...

Closed-Form Expression of the Fourier Ring-Correlation for Single-Molecule Localization Microscopy

Michaël Unser, Daniel Sage, Thanh-An Michel Pham, Emmanuel Emilien Louis Soubies

Single-molecule localization microscopy (SMLM) is a popular microscopic technique that achieves super resolution imaging by localizing individual blinking molecules in thousands of frames. Therefore, the reconstructed high-resolution image is a combination ...

Parameter-free image resolution estimation based on decorrelation analysis

Aleksandra Radenovic, Adrien Charles-François Raymond Descloux, Kristin Stefanie Grussmayer

Super-resolution microscopy opened diverse new avenues of research by overcoming the resolution limit imposed by diffraction. Exploitation of the fluorescent emission of individual fluorophores made it possible to reveal structures beyond the diffraction l ...

Diffractive Optical Elements Investigation in the Phase Domain

Myun Sik Kim, Toralf Scharf, Michail Symeonidis, Dong Cheon Kim

In this work we demonstrate the advantages of investigating diffractive optical elements in the phase domain. In this regime we can detect features that are not restrained by the diffraction limit and relate them to the geometrical and optical properties o ...

Imaging tissues and cells beyond the diffraction limit with structured illumination microscopy and Bayesian image reconstruction

Tomas Lukes, Jakub Pospisil

Background: Structured illumination microscopy (SIM) is a family of methods in optical fluorescence microscopy that can achieve both optical sectioning and super-resolution effects. SIM is a valuable method for high-resolution imaging of fixed cells or tis ...

Biomedical optical techniques for intracochlear cellular imaging

Marilisa Romito

Imaging the inner ear microanatomy is of great importance for the assessment of the state of the cells responsible for sound detection. Hearing disorders are mainly due to a malfunction of the cochlea, the bone containing the cells inside the inner ear. Un ...

Waveguide-PAINT offers an open platform for large field-of-view super-resolution imaging

Aleksandra Radenovic, Suliana Manley, Anna Archetti, Evgenii Glushkov, Anton Stroganov

Super-resolution microscopies based on the localization of single molecules have been widely adopted due to their demonstrated performance and their accessibility resulting from open software and simple hardware. The PAINT method for localization microscop ...

Dielectric-sphere-based microsystem for optical super-resolution imaging

Gergely Huszka

Well-established imaging techniques proved that features below the diffraction limit can be observed optically using so-called super-resolution microscopies, which overcome Abbe's resolution limit. In traditional far-field microscopy, the introduction of f ...

Combined Multi-Plane Tomographic Phase Retrieval and Stochastic Optical Fluctuation Imaging for 4D Cell Microscopy

Marcel Leutenegger, Theo Lasser, Hilal Lashuel, Adrien Charles-François Raymond Descloux, Emrah Bostan, Arno Pino Bouwens, Anne-Laure Mahul Mellier, Tomas Lukes

Super-resolution fluorescence microscopy provides unprecedented insight into cellular and subcellular structures. However, going beyond the diffraction barrier comes at a price since most far-field super-resolution imaging techniques trade temporal for spa ...

Looking beyond Pixels : Theory, Algorithms and Applications of Continuous Sparse Recovery

Hanjie Pan

Sparse recovery is a powerful tool that plays a central role in many applications, including source estimation in radio astronomy, direction of arrival estimation in acoustics or radar, super-resolution microscopy, and X-ray crystallography. Conventional a ...

Structural and functional brain imaging using extended-focus optical coherence tomography and microscopy

Paul James Marchand

Neuroimaging techniques aim at revealing the anatomy and functional organisation of cerebral structures. Over the past decades, functional magnetic resonance imaging (fMRI) has revolutionized our understanding of human cerebral physiology through its abili ...

A Nonsmooth Graph-Based Approach to Light Field Super-Resolution

Pascal Frossard, Mattia Rossi, Mireille El Gheche

In this article we propose a new super-resolution algorithm tailored for light field cameras, which suffer by design from a limited spatial resolution. To do so, we cast the light field super-resolution problem into an optimization problem, where the parti ...
