Image Storage, but Not Without Delay

Facebook X LinkedIn Email
Slow and steady really does win, according to University of Rochester researchers. The group slowed images carried on photon pulses in a hot gas of atoms and then showed that the image information was preserved. As described in the Jan. 26 issue of Applied Physics Letters, this go-slow, all-optical image delay could find use in image processing, holography, optical pattern correlation, remote sensing and quantum information. For example, image processing requires a buffer. One solution is to convert the image to its electronic equivalent, but because that demands lots of light, information...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
