Nanoparticle Scattering Leads to Transparent Projection Screen

Facebook X LinkedIn Email
A new class of transparent projection screens could bring vehicle and aircraft navigation, advertising – even eyeglasses – to a whole new level. A team from MIT, the Harvard departments of Physics and the U.S. Army Edgewood Chemical Biological Center has developed an inexpensive transparent projector screen using a resonant nanoparticle scattering technique. Nanoparticles that interact with a single color (in this case, blue) are incorporated into a transparent material. The result is a material that lets most of the ambient light go through and, therefore, appears...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.
