Ultraviolet wireless optical comunication is a short-distance communication method with great potential.This paper analyzes ultraviolet air transmission features and system signal path model,uses ultraviolet scattering property to realize anti-intervention non-line-of-sight communication,chooses ultraviolet LED and electron-multiplier phototube as litht source and optoelectronic detector of communication system respectively and applies pulse coding modulation and cyclic redudancy encoding method to design and make a set of ultraviolet wireless optical communication system prototype so that small angle real-time data communication is achieved transmit rate is 9.6 kbps,deviation is 1 percent,communication ditance is inside 5 meters.
