Short-Range UV Communication Links.

摘要

The solar blind ultraviolet (UV) portion of the spectrum can be used for short range communications. A UV communication link of distance of 0.75km has been set up at Naval Ocean Systems Center, San Diego, and has been operating for more than a year. Of all the meteorological parameters that affect link performance, the most important is the terrestrial ozone concentration. The UV link can be operated in either the line-of-sight (LOS) or the non-line-of-sight (NLOS) mode. For average values of ozone concentration, with data rate of 2400 baud, BER =-5, the range is 1 km for NLOS and 3 km for LOS. Reprints. (r.r.h.)
