Holographic imaging of electromagnetic fields using electron-light quantum interference

In conventional holography a photographic film can record the interference pattern of monochromatic light scattered from the object to be imaged with a reference beam of un-scattered light. Scientists can then illuminate ...

New holographic technique opens the way for quantum computation

Photography measures how much light of different color hits the photographic film. However, light is also a wave, and is therefore characterized by the phase. Phase specifies the position of a point within the wave cycle ...

Deep learning merges advantages of holography and bright-field microscopy for 3-D imaging

Digital holographic microscopy is an imaging modality that can digitally reconstruct the images of 3-D samples from a single hologram by digitally refocusing it through the entire 3-D sample volume. In comparison, scanning ...

Physicists create Star Trek-style holograms

Star Trek's famous holodeck is a virtual reality stage that simulates any object in 3-D as if they were real. However, 3-D holographic projection has never been realized. A team of scientists from Bilkent University, Turkey, ...

In-plane coherent control of plasmon resonances for plasmonic switching and encoding

Light incident on metallic nanoparticles can initiate the collective motion of electrons, causing a strong amplification of the local electromagnetic field. Such plasmonic resonances have significant roles in biosensing with ...

A big step toward the practical application of 3-D holography with high-performance computers

Japanese computer scientists have developed a special purpose computer that can project high-quality three-dimensional (3-D) holography as video. The research team led by Tomoyoshi Ito, who is a professor at the Institute ...

Digital in-line holography helps researchers 'see' into fiery fuels

Transportation accidents, such as trucks crashing on a highway or rockets failing on a launch pad, can create catastrophic fires. It's important to understand how burning droplets of fuel are generated and behave in those ...

3-D digital holography of moving objects at a million frames per second

A million frames per second has been achieved in 3D digital holography of moving objects. The method, developed at Kyoto Institute of Technology in Japan, could be used to analyse high-speed phenomena, including plasmas and ...

Electron holography of individual proteins

Proteins are the tools of life. In future, scientists may be able to examine single molecules with an especially gentle method to determine how they are constructed, how they perform their functions in cells, and how they ...

Quasi noise-free digital holography

Noise originating from the coherent nature of laser light is the scourge of digital holography, reducing the quality of holographic images below that of conventional photographs. Now, Pasquale Memmolo of ISASI-CNR and collaborators ...
