Paper Abstract

Short range non-line-of-sight (NLOS) ultraviolet (UV) communication, with its solar blind and Non-Line-of- Sight characteristic, received grant interest. However as the communication range increases, the communication performance deteriotes due to NLOS UV turbulence, even with special UV turbulence mitigation. In this work, we conducted a series of outdoor experiments to investigate the received signal energy distribution, which is the product of the complex interaction of transmitted UV radiation, by utlizing both a UV LED array and a UV laser, with the atmosphere. Separation distance, pointing angles and UV light source were taken into considerate as key parameters to affect the distribution. These experimental results will be valuable for studying NLOS UV communication performance.
