In 1873, Ernst Abbe proposed the famous diffraction limit theory, stating that the resolution of an optical system is limited by the light wavelength ...

The imaging resolution has long been constrained by the Abbe-Rayleigh diffraction limit. While the 2014 Nobel Prize recognized fluorescence microscopy, achieving single-shot, label-free far-field ...

If you are leasing a car, what’s the point of paying thousands of dollars due at lease signing? My contract says tax, title, fees and licensing — but then wouldn’t I have to pay that again at the end ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...

Ptychography is an area-by-area scanning method that uses constant, coherent illumination to scan a region of a sample in several adjacent and overlapping locations. The dispersed radiation is ...

Crystallography is the science of analyzing the pattern produced by shining an X-ray beam through a material sample. A powder sample produces a different pattern than solid crystal. One longstanding ...

Attosecond science, honored with the 2023 Nobel Prize in Physics, is transforming our understanding of how electrons move in atoms, molecules, and solids. An attosecond—equivalent to a billionth of a ...

Abstract: Although WiFi-based contactless sensing has made significant progress in the past decade, most prior work still focus on the reflection zone far from WiFi transceivers, while few studies ...

Last month, I met my friend for coffee, where I was introduced to a popular term used in the world of HR: frequent applier. My friend, let’s call her Joy, is the head of hiring at a DC-based ...

[The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along ...
