Pushing optical imaging below the diffraction limit usually requires complicated illumination schemes and still suffers from weak, unstable signals ...

Nanoscopy is a field of microscopy that focuses on imaging and studying structures and processes at the nanoscale, typically below the diffraction limit of light. It encompasses various techniques ...

Achieving optical imaging beyond the diffraction limit imposed by a single finite aperture remains an important objective in astronomy, remote ...

(a) Working principle of metasurface displacement measurement can be understood as the detection of the power of different modes of the converted light. The incident irradiated on the metasurface and ...

What is Single-Molecule Localization Microscopy? Single-molecule localization microscopy (SMLM) is a super-resolution imaging technique that enables the visualization of biological structures and ...

ISM is a super-resolution imaging technique that enhances resolution beyond the diffraction limit through pixel reassignment and deconvolution. However, the practical implementation of ISM requires ...

Processes in the human body are shaped by the interaction of various biomolecules, such as proteins and DNA. These processes take place in a range of often just a few nanometers. They can therefore no ...
