讨论了抽运光功率和重复频率对激光脉宽的影响。

The results of the simulation analysis and experiments indicate that the loss of ultraviolet scattering transmission in atmosphere is high because of the particle scattering and absorbing in solar-blind zone; that is, the received power can descend 20 dB with the distance increasing 10 times. Therefore, the ultraviolet scattering is fit for short range communication. In short range, the pulse extension due to scattering is at microsecond order and its influence for low and moderate bit rate communication systems is weak. Since the light output power of a single ultraviolet LED is low, a multi-LED array can be used to increase the transmit power and extend the communication range.

仿真分析与实验结果显示：日盲区紫外光在大气中散射传输时由于大气粒子的强烈散射与吸收，传输损耗较大，距离每增加10倍，接收功率下降20dB，因此日盲区紫外光大气散射通信适用于近距离通信场合；近距离传输时散射造成的光脉冲多径展宽为微秒量级，对中低速通信系统影响较小；单个紫外LED发光功率较低，可通过多个LED阵列来提高发射功率，增大通信距离。
