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.
Coded aperture imaging (CAI) is another incoherent imaging technique developed in the 20th century to achieve lensless 2D imaging with nonvisible wavelengths. In CAI, the light from an object is modulated by a coded mask ...
Researchers in Singapore have developed the world's smallest LED (light-emitting diode) that enables the conversion of existing mobile phone cameras into high-resolution microscopes. Smaller than the wavelength of light, ...
Modern-day technologies like optical computing, integrated photonics, and digital holography require light signals to be manipulated in three dimensions. To achieve this, it is necessary to be able to shape and guide the ...
Holography—the use of light projection to display images—can be used to construct holograms, which are three-dimensional structures of light that depict true-to-life objects and scenes. While today's technologies can't yet ...
Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. By packing more details into a 3D image, this type of hologram could enable realistic representations of the world around ...
In the era of big data, global data volume is growing exponentially. The development of numerous technologies depends on massive data and also generates massive data. Data mining, storage, and protection are becoming increasingly ...
As fundamental properties of light, spectra and polarization carry vital information concerning the propagation of light waves. For example, spectral imaging can reflect the material composition of objects, while polarized ...
Red tides, caused by Karenia brevis blooms, are a recurring problem in the coastal Gulf of Mexico. The organism, Karenia brevis, produces toxins that can cause fish kills, respiratory irritation in humans and cause death ...
Having more tools helps; having the right tools is better. Utilizing multiple dimensions may simplify difficult problems—not only in science fiction but also in physics—and tie together conflicting theories.
