[Also in Division G1] An optical communication system (utilizing the Zeeman or Stark effects) comprises a transmitter 20 (Fig. 1) having an energy source 25, with a transmission frequency in the infra-red, visible or ultra-violet regions of the electromagnetic spectrum, the source being ...
A method is provided for forming a photoactive coating having a photoabsorption band in the visible region of the electromagnetic spectrum. The method includes depositing a precursor composition over at least a portion of a float glass ribbon in a molten metal bath by a CVD coating device. The...
The visible and near-infrared regions of the electromagnetic spectrum have been widely applied as leading spectral bands in remote sensing. This is because the visible and near-infrared bands exist to a larger extent, with respect to other bands, within the region of the highest and largest amou...
