Our understanding of the universe may not be expanding as much as the universe itself. In some cases, our theories about cosmic inflation may feel as if they are deflating into a black hole.
A team of researchers at University College London has developed a way to keep objects levitated by sound waves airborne when other objects interfere with the levitation path. In their paper published in the journal Science ...
Holographic interferometry is the technique of measuring stress, strain, and vibration with light. It is defined by the wavelength of light, finding flaws in structural bonds. It makes full use of a hologram's ability to ...
A new publication in Opto-Electronic Advances overviews dynamic metasurfaces and metadevices empowered by graphene.
Nature may abhor a vacuum, but it sure loves structure. Complex, self-organized assemblies are found throughout the natural world, from double-helix DNA molecules to the photonic crystals that make butterfly wings so colorful ...
Today's society generates ever more internet data traffic for applications such as ultra-high-definition video, cloud services and 5G mobile connections. This decades-long continual exponential growth of data traffic has ...
In conventional holography, the hologram is formed by recording the interference fringes of two coherent beams using a photosensitive material. The amplitude and phase information of the original signal wave can be reconstructed ...
Opto-Electronic Science has published a study expanding infrared microspectroscopy with the Lucy-Richardson-Rosen computational reconstruction method.
Holograms are three-dimensional (3D) images produced by interfering beams of light that reflect physical objects or photographs. In recent years, they were introduced in a variety of settings, for instance to enhance employee ...
A newly proposed technique enables rapid 3D image acquisition. One-scan is a technique involving an elongated light spot that resembles a "needle" which captures three-dimensional (3D) images of a specimen.
