title: Design of an omnidirectional optical antenna for ultraviolet communication.
abstract: In this paper we propose an omnidirectional large field-optical antenna with a dual-mirror structure and field devices and demonstrate its utilization in ultraviolet (UV) communications. Theoretical analysis shows that it is suitable for short-range UV communication. Simulation indicates that the optical gain is 32, and the system has a good spot uniformity. Additionally, incident angles of incident ray meet the requirement of the interference filter (±10°). Outdoor experiments show that the angle of FOV is in the range of ±20°~±80° and a SNR increase of 31 dB compared with bare tube is observed, demonstrating the effectiveness of the omnidirectional optical antenna structure for free-space UV communication.
