A new research study from Opto-Electronic Advances discusses tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography. In recent years, the scientific ...

Jan. 27 (UPI) --University of Rochester researchers have developed a novel beam pattern that promises to lend unprecedented sharpness to ultrasound and radar images. The beam's mathematical pattern ...

Whorls of FLASH: (a) Optimized scan patterns; (b) comparison of standard (non-optimized) line-by-line and scan-pattern optimized (SPO) patterns. The resulting pencil-beam scanning dose rate (PBS-DR) ...

The Nobel Prize in Chemistry 2014 was awarded for the development of super-resolved fluorescence microscopy. Inspired by this work, scientists at Institute of Photonic Chips (IPC), University of ...

Beams of light polarized into spirals have been used by scientists in the UK to create intricate patterns on the surface of metals. This is the first time that these “logarithmic spirals” have been ...

Mass migration of photo-isomeric azo-polymers occurs according to the light intensity gradient, and the morphological surface structure can be fabricated by the artificial distribution of light by ...

A new beam pattern could bring unprecedented sharpness to ultrasound and radar images, burn precise holes in manufactured materials at a nano scale -- even etch new properties onto their surfaces. A ...
