Ultraviolet UV systems provide unique opportunities for communications and sensing. We present recent results in UV communications, including experiments and analysis. We describe our experimental ultraviolet communication test-bed based on light emitting diodes with divergent beams, a solar blind filter, and a wide field-of-view detector. Then we report on statistical models for noise and signal photon counts, non-line of sight NLOS short-range ultraviolet communication link losses, and performance of photon counting detectors, operating in the solar blind spectrum regime. The effects of transmitter and receiver elevation angles, separation distance, and path loss are included. We also demonstrate shot-noise limited bit-errorrate performance, showing good agreement with analytically predicted performance.
