Sparse holography: A novel method for creating 3D images

Computational imaging has seen tremendous progress in the last decade. The process involves using a combination of advanced algorithms and hardware to create images that cannot otherwise be captured by traditional cameras.

New technique takes 3-D imaging an octave higher

A collaboration between Colorado State University and University of Illinois at Urbana-Champaign resulted in a new, 3-D imaging technique to visualize tissues and other biological samples on a microscopic scale, with potential ...

Nanotechnology delivers hepatitis B vaccine

Brazilian and European researchers have demonstrated exactly how a nanotechnology-based compound delivers an oral vaccine against hepatitis B to the immune system. When particles containing silica and an antigen combine, ...

New method to create ultrafast 3-D images of nanostructures

Lensless microscopy with X-rays, or coherent diffractive imaging, is a promising approach. It allows researchers to analyse complex three-dimensional structures, which frequently exist in nature, from a dynamic perspective. ...

Egyptian mummies virtually unwrapped in Australia

The hidden secrets of Egyptian mummies up to 3,000 years old have been virtually unwrapped and reconstructed for the first time using cutting-edge scanning technology in a joint British-Australian exhibition.

Mini X-ray source with laser light

Physicists from Ludwig-Maximilians-Universit√§t, the Max Planck Institute of Quantum Optics and the TU M√ľnchen have developed a method using laser-generated X-rays and phase-contrast X-ray tomography to produce three-dimensional ...
