为提高多屏测试系统的稳定性和可靠性，研究了多屏目标光信息传输链路特性和远距离传输性能，在激光多屏测试系统几何模型和可见光信息通信原理的基础上，建立了离散多音调制传输模型;分析了目标光信息通信系统中发送器和接收器的电光和光电转换功能，研究了广义可见光通信信道的目标信息传输性能和传递函数;建立了光信息通信传输链路光强空间分布模型和分布函数，推导了信息传输通信系统信噪比模型。通过计算和实验分析，结果表明：在一定的信道调制深度下，传输误码率随传输速率的增加而增加，当选择合适的传输速率时，误码率可达0.01。
To enhance the stability and reliability of multi-screens testing system, this paper studies multi-screens target optical information transmission link properties and performance in long-distance, sets up the discrete multi-tone modulation transmission model based on geometric model of laser multi-screens testing system and visible light information communication principle; analyzes the electro-optic and photoelectric conversion function of sender and receiver in target optical information communication system; researches target information transmission performance and transfer function of the generalized visible-light communication channel; found optical information communication transmission link light intensity space distribution model and distribution function; derives theSNRmodel of information transmission communication system. Through the calculation and experiment analysis, the results show that the transmission error rate increases with the increment of transmission rate in a certain channel modulation depth; when selecting the appropriate transmission rate, the bit error rate reach 0.01.
