ABSTRACT:
A method and apparatus for high speed transmission of data in the solar blind region is disclosed. An ultraviolet source is modulated to permit digital transmission of data. The source includes an electrodeless capsule of UV transmitting material filled with iodine vapor. A means of energizing the iodine vapor into a plasma state is provided by a magnetron, power triode or solid state supply. A circuit to modulated the energizing means is used to impress upon the plasma discharge the encoded data. Filtering means surround the capsule to filter out the plasma background noise. The advantages of the UV communications method and apparatus described are increased pulse rate, faithful conversion of electrically pulsed data into optical pulses with decreased error rate, decreased probability of interception and non-line of sight communication.
