(Nanowerk News) Until recently, it was widely believed among physicists that it was impossible to compress light below the so-called diffraction limit (see fact box), except when using metal ...

Researchers from the University of Science and Technology of China (USTC) led by Prof. ZHANG Douguo have unveiled a planar optical device that significantly enhances the capabilities of dark-field ...

The Abbe diffraction barrier, which fundamentally restricted the lateral optical resolution to 200 – 300 nm until the early 1990s, can be overcome by super-resolution optical fluorescence imaging ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

Researchers built a silver-grooved chip that channels laser energy into nanometer-spaced peaks, beating the diffraction limit and aiding light-matter studies. (Nanowerk News) Physics is full of pesky ...

When you think about highly-precise actuators, stepper motors probably aren’t the first device that comes to mind. However, as [Diffraction Limited]’s sub-micron capable micro-manipulator shows, they ...

Attempts to break the diffraction limit with 'super lenses' have all hit the hurdle of extreme visual losses. Now physicists have shown a new pathway to achieve superlensing with minimal losses, ...

Compared with the superresolution microscopy that bases on squeezing the point spread function in the spatial domain, the superresolution microscopy that broadens the detection range in the spatial ...

Advancements in quantum imaging are transforming scientific research, offering unprecedented resolution and sensitivity for ...
