Super-resolution FRET measurements
Nanoscale, 2021Recent advances combining FRET and super-resolution techniques are presented. This merger of methods is opening exciting opportunities to study the spatial organization and functional state of (bio)molecules and materials at the nanoscale.

The in situ, nanoscale positioning of a single molecule below the diffraction limit remains a challenge for chemists. Now, two approaches show how this can be accomplished through a combination of super-resolution microscopy and photo-inducible crosslinking chemistry.

Resolution and super‐resolution
Microscopy Research and Technique, 2017AbstractMany papers have claimed the attainment of super‐resolution, i.e. resolution beyond that achieved classically, by measurement of the profile of a feature in the image. We argue that measurement of the contrast of the image of a dark bar on a bright background does not give a measure of resolution, but of detection sensitivity.

Physics Letters A, 2003
In 1952 Toraldo di Francia [Il Nuovo Cimento (Suppl.) 9 (1952) 426] proposed an intriguing concept to increase the optical resolving power. As a consequence, this theory could seem in contradiction with Heisenberg's uncertainty principle. In this Letter we report on the results of a microwave investigation which demonstrate the rightness of such ...

The objective of this work is to increase the range resolution of time-of-flight (ToF) cameras. Our work aims to produce a super-resolution depth map and reduce the depth error within the whole work volume using a novel multi-exposure data acquisition technique and Projection Onto Convex Sets(POCS) reconstruction.

Inception learning super-resolution
Applied Optics, 2017An efficient network for super-resolution, which we refer to as inception learning super-resolution (ILSR), is proposed. We adopt the inception module from GoogLeNet to exploit multiple features from low-resolution images, yet maintain fast training steps.

Signal Recovery and Synthesis IV, 1992
We may define super-resolution as the ability to form an image with meaningful spatial frequency content at spatial frequencies for which the optical instrument has an optical transfer function (OTF) equal to zero. The 1964 paper by J. Harris1 showing that no two distinct, finite sized objects could result in the same (ordinary) focal plane image, no ...

Super-Sampling by Learning-Based Super-Resolution
International Journal of Computational Science and Engineering, 2018In this paper, we present a novel problem of intelligent image processing, which is how to infer a finer image in terms of intensity levels for a given image. We explain the motivation for this effort and present a simple technique that makes it possible to apply the existing learning-based super-resolution methods to this new problem.

Fluorescent resolution target for super‐resolution microscopy
Journal of Microscopy, 2003SummaryHistorically, resolution in fluorescence optical microscopy has been limited by the Rayleigh criterion. Recently, however, several techniques have achieved resolution below that specified by the Rayleigh criterion. Among these are 4‐Pi confocal microscopy, harmonic excitation light‐microscopy, stimulated emission depletion microscopy, near‐field
