... by gravity. But scientists are now investigating how to make light beams into looped and knotted configurations. The possibility for these structured light beams arises from some curious solutions to Maxwell`s equations, which describe the fundamentals of electricity ...
(PhysOrg.com) -- Intel today announced an important advance in the quest to use light beams to replace the use of electrons to carry data in and around computers.
... , our detectors gather additional information on the phase of the light beam." The device's ability to detect and distinguish ... to couple any type of free-space light beam into any type of surface wave ...
... of faint objects and improved amplification and positioning of light beams, the researchers' technique for producing quantum ... . To satisfy nature's requirement for the set of outgoing light beams to have the same energy and momentum as the set ...
... convenient and flexible method for creating twin light beams, researchers from the National Institute of Standards and Technology (NIST) and the University of Maryland (UM) have produced ...
... fork. "We match the pulse frequency of the illuminating light with the mechanical resonant frequency of the quartz crystal ... ." The amplitude of this vibration is proportional to the intensity of the scattered light beam falling on the tuning fork, which because ...
... machinery: Gently tugging them apart with light beams. "It's really giving us a molecular ... of Sciences. Last fall, Lang and others demonstrated that light beams could be used to pick up and move individual cells ...
Researchers have developed a novel technique to measure the strength of the bonds between two protein molecules important in cell machinery: gently tugging them apart with light beams.
... flying objects a quarter mile to a half mile up is no easy task. They have used stationary light beams, radar-mounted tracking spot ... or she looked for other objects entering the radar's beam. If another potential target appeared, the radar ...
... of the Eustachian tubes was more readily observed by directing a light beam at the mouth from under the frog's chin. When the Eustachian tubes were open, the light was visible through the eardrum. When they closed, the circles ...
... are often considered to be highly directional light sources: their beams are able to propagate over long distances ... around small obstacles or apertures. Light beams endure strong diffraction when emerging from the small ...
... have known that liquid columns can be used to guide light. By trapping a light beam, a liquid column can act like an optical fiber, but with a liquid sheathing instead of glass ...
(PhysOrg.com) -- Researchers at the University of St Andrews have made a surprise discovery using light beams that can travel around corners.
... . Using a technology called near infrared spectroscopy, which is able to penetrate the skull with high-powered light beams to assess oxygen saturation, they measured ...
... at MGH-Wellman. Inside a fiberoptic probe, a constantly rotating laser tip emits a light beam with an ever-changing wavelength. As the probe moves through the structure to be imaged, measuring how each ...
