If the communication is optical, then the computation might be done optically as well.
If this band gap is larger than optical light energies, these ceramics will be optically transparent (although powders and porous compacts of such ceramics will be white and opaque due to light scattering).
When such manipulation is desired, a software program performs the optical character recognition (OCR) function by converting each optically scanned character into an electric signal and comparing it with the internally stored representation of an alphabet of characters, so as to select from it the one that matches the scanned character most closely or to reject it as an unidentifiable token.
Optically, the substance behaves like a crystal with its optic axis parallel to the electric field.
Back at the beginning of the show, across a floor whose size is accentuated by a geometric pattern of yellow, grey and black shapes that optically flip perspective as you look at them, a ventriloquist's dummy sits on a shelf, dangling his legs in the air.
Since, optically speaking, energy levels correspond to wavelengths, such an arrangement can be tweaked to reflect some wavelengths and preferentially emit others.
Although it is correct that using a paper ballot that can be optically scanned is the best method to achieve openness and reliability, what is also needed is a robust audit programme across every jurisdiction that provides a comprehensive review of the election processes from beginning to end.
Dr Perrig says this would reduce the cost of kit, and make SCION feasible for optically switched networks in which current route computation is just not possible.
Since October 1st, all Mexicans crossing the border have had to carry a card that includes not only a photograph but biometric data which can be optically scanned.
While the number of accidents caused by straying into an adjacent lane is relatively small, such incidents account for a surprisingly high 10,300 deaths a year.Lane-departure warning systems work by optically tracking lane markers using a digital camera, and then vibrating the steering wheel or making a drumming noise when the driver drifts wide.
