The rapid development of new sources of coherent X-rays, such as third-generation synchrotrons, high-harmonic-generation lasers1 and X-ray free-electron lasers2, has led to the emergence of the ...

The diffractive microrelief pattern on the plane side of the lens gives a diffraction-limited spot size that demonstrates a sharp focusing effect and a dramatic increase in power densities, even for ...

Diffractive deep neural networks (D 2 NN), also known as diffractive networks, constitute an emerging optical computing architecture. These task-specific networks are constructed from spatially ...

UCLA researchers have introduced a framework for synthesizing arbitrary, spatially varying 3D point spread functions (PSFs) using diffractive ...

Posted: May 29, 2015: Beyond crystallography: Diffractive imaging using coherent x-ray light sources (Nanowerk News) In 1999, UCLA professor John Miao pioneered a technique called coherent diffractive ...

The researchers propose using diffractive solar sails for controlling and placing satellites in difficult but useful orbits around the earth and for interesting and useful orbits around the sun. An ...

Diffractive optical neural networks, for instance, are designed using deep learning to perform optical computing with high power efficiency, faster processing, and scalability.

“We published a paper on 3D diffractive optics several years ago, but these devices are difficult to reconfigure dynamically. If you can control the device with a computer, it will make it that much ...

We have had diffractive optics for 25 years, and they have improved significantly but have done so by decreasing the near add. When these lenses were initially introduced, we had a +4 D add, with ...

Now you see it: A schematic of the experiment, in which an optical diffractive camera hides information by concealing it within ordinary-looking “dummy” patterns. (Courtesy: A Ozcan) Information ...
