摘要
介绍了非视线紫外光传输模型,利用Monte-Carlo方法对非视线紫外光传输过程进行模拟,分别讨论了能见度、降雨量、风速、光源发射功率、探测器灵敏度对传输距离的影响。结果显示能见度、降雨量对传输距离影响较大,风速几乎毫无影响;随着探测器灵敏度的提高,传输距离增大很快;而当光源功率增大到一定程度后,传输距离的增大不明显。对非视线紫外光传输系统的设计提供了依据。
Model of non-line-of-sight（NLOS） UV transmission is introduced. NLOS UV transmission is simulated by using Monte-Carlo method. Effects of visibility, rainfall, wind speed, light source transmitted power and detector sensitivity on transmission range are discussed respectively. Results show that visibility and rainfall have relative effect on transmission range, while wind speed has no influence. The transmission range increases very fast with the detector sensitivity increase. When the light source transmitted power is much higher, the transmission range increases slowly. It provides the basis for the design of the non-line-of-sight UV transmission.
