利用蒙特卡罗方法对紫外光非视距传输过程进行了模拟,讨论了传输过程中固体角的确定,仿真分析了系统的角度设置对传输损耗的影响。结果表明,增大收发仰角可以降低系统的传输损耗,并且小角度集中发射与大视场角接收可以降低系统的传输损耗。 The non-line-of-sight transmission process of ultraviolet light was simulated by Monte Carlo method. The determination of solid angle during transmission was discussed. The influence of system angle setting on transmission loss was analyzed. The results show that increasing the transmit / receive elevation can reduce the transmission loss of the system, and the small-angle concentrated emission and wide-angle reception can reduce the transmission loss of the system.
