Abstract
Considering the slow modulation rate and large volume of the gas lamp and the laser, and the high working voltage of the photomultiplier tube (PMT) in UV communication, a solar blind ultraviolet LED real-time video transmission system based on Field Programmable Gate Array (FPGA) was proposed, which utilized single UV LED with wavelength of 265 nm at the transmitter and an UV PIN at the receiver. The video transmission system was established by designing the circuit and logic module. The relationship between the optical power density and the communication distance of the communication system was investigated. The experimental results show that the maximum transmission rate is 2.88 Mbit/s, when the communication distance is 4 m, the transmission rate can be up to 1.92 Mbit/s based on the mode of On-Off Keying (OOK) modulation for the system.
