Paper Abstract

A He-Ne laser communication system with video bandwidth capability is described. The system is suitable for the transmission of video signals generally compatible with U. S. commercial practice and the transmission of digital data at rates of approximately 10 to 1000 Kb/s, over ranges extending from a few hundred feet to several miles. The system utilizes an externally modulated He-Ne laser, direct detection with a photomultiplier tube and a frequency modulated subcarrier method for coping with the dynamic fade due to atmospheric turbulence. Use experience indicates that such systems perform according to specification in a variety of applications and over a wide range of weather conditions.
