(Phys.org) —Swinburne University of Technology researchers have shown the potential of a new material for transforming secure optical information storage.
(Phys.org) —Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like design decorated ...
Subtle surface signs reveal when and where sunspots will emerge on the Sun, at least a day in advance, according to a team of researchers led by Northwest Research Associates (NWRA). The results were presented in science ...
To test the severity of a viral infection, clinicians try to gauge how many viruses are packed into a certain volume of blood or other bodily fluid. This measurement, called viral load, helps doctors diagnose or monitor chronic ...
(Phys.org) —It is widely known that the optical properties of certain materials can be modified by using lasers to control the quantum states of their optical electrons. Lasers that can generate ultra-short pulses in the ...
Fancy watching a movie on your mobile phone, where figures leap out from the screen in 3D, rather as Princess Leia did in that scene from "Star Wars"? That's the claim made by US researchers, who on Wednesday reported they ...
In the world of microscopy, this advance is almost comparable to the leap from photography to live television. Two young EPFL researchers, Yann Cotte and Fatih Toy, have designed a device that combines holographic microscopy ...
(Phys.org)—No need to turn to your smartphone to check the time, look at your agenda or the weather forecast, read a text message or map a route in an unfamiliar city. All this information, and much more, will soon be displayed ...
As striking as it is, the illusion of depth now routinely offered by 3-D movies is a paltry facsimile of a true three-dimensional visual experience. In the real world, as you move around an object, your perspective on it ...
