Electrodeless ultraviolet communications system

The Laser Communications Laboratory (LCL) of the Wright Laboratory Avionics Directorate is heavily involved in designing optical communications systems covering the full optical spectrum to meet our current and future military communications requirements. This paper summarizes the in-house designed and built solar blind ultraviolet communications system used in the LCL to investigate non-line-of-sight data and voice links. It also summarizes some of the previous DoD work accomplished to exploit free space communications via ultraviolet radiation. In addition, safety factors peculiar to ultraviolet radiation in a closed cockpit environment are addressed. An evaluation of the current electrodeless ultraviolet communications system and a synopsis of planned future projects to improve the system are included in the paper.<
