USING a specially constructed rectifier giving 1,100 volts and a Taylor T 55 valve with amphenol bases and special inductances, frequencies up to 100 megacycles per second have been produced. A ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Two become one: various diffraction patterns showing Rayleigh's criterion. (Credit: Wikimedia Commons/Spencer Blevin) Scientists have long believed that diffraction limits the minimum distance that ...

Structured Illumination Microscopy (SIM) is a tool which breaks the diffraction resolution barrier to provide resolutions of up to 20nm. The resolution of conventional microscopes is limited by the ...

Researchers have developed a new algorithm for recovering the 3D refractive index distribution of biological samples that exhibit multiple types of light scattering. Researchers have developed a new ...

Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

Near-field optics operates on the principle that when light interacts with objects smaller than its wavelength, it can produce an evanescent wave that decays exponentially with distance but provides ...

Researchers have developed a light diffraction technology that allows for more light input and greater efficiency, an advance that could lead to more immersive augmented reality displays. Diffraction ...

Inprentus provides beamline scientists with the world’s most advanced diffraction gratings for x-ray applications, offering unparalleled efficiency and high resolving power Champaign, Illinois, USA, ...
