Researchers have developed a 3D full-color display method that uses a smartphone screen rather than a laser to create holographic images. With further development, the new approach could be useful for augmented or virtual ...
There are many ways to store data—digitally, on a hard disk, or using analog storage technology, for example as a hologram. In most cases, it is technically quite complicated to create a hologram: High-precision laser technology ...
Researchers have made a significant breakthrough in controlling the polarization of light, a crucial property for various applications such as augmented reality, data storage, and encryption.
According to a recent study from the University of Helsinki, published in the journal Physical Review Letters, a vortex of a superfluid that has been quantized four times has three ways of dividing, depending on the temperature.
Information security has become particularly crucial under the background of the big data era. Optical secret-sharing schemes encrypt information and physically divide it into different shares. Information can only be decrypted ...
In the realm of optical holography, the conventional limitations of polarization, wavelength, and incident angle are giving way to a new era of possibilities. A breakthrough technique known as optical orbital angular momentum ...
Light, as an electromagnetic field, has two essential components: amplitude and phase. However, optical detectors, usually relying on photon-to-electron conversion (such as charge-coupled device sensors and the human eye), ...
Researchers at the University of Warsaw's Faculty of Physics with colleagues from Stanford University and Oklahoma State University have introduced a quantum-inspired phase-imaging method based on light intensity correlation ...
A quarter century ago, physicist Juan Maldacena proposed the AdS/CFT correspondence, an intriguing holographic connection between gravity in a three-dimensional universe and quantum physics on the universe's two-dimensional ...
Femtosecond transient microscopy is an important tool to study ultrafast transport properties of excited states in solid-state samples. Most implementations are limited to photoexciting a single diffraction-limited spot at ...
