1. Introduction UV wireless optical communication is a technology that utilizes UV light sources for data transmission and communication in the atmosphere [1]. This method is based on the unique properties of UV light to transmit information through the atmosphere and is typically used for short-range, high-speed communication, serving as an important supplement to conventional communication methods.

1. Introduction UV wireless optical communication technology has garnered significant attention for its potential to offer large transmission bandwidths and resistance to electromagnetic interference. UV communication operates within the “blind to daylight” band (200–280 nm), demonstrating robust performance in environments with strong solar background radiation, overcoming challenges posed by background light noise in visible and infrared bands.
