A new plasmonic fiber probe uses linearly polarized light and energy recycling for broadband nanofocusing with resolution ...

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 ...

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

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

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 ...

(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 ...

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 ...
