摘要
由于光波通信具有无线电通信无法比拟的优点,在通信领域中起着至关重要的作用,所以利用电光调制的原理设计了一激光通信系统。将被传输的信号作为调制信号加在电光晶体上,在接收端接收被调制的光信号,之后进行解调、还原,用光波来传递信息。并且做了相关的通信实验,证明了用电光调制技术进行激光通信的可行性。由于实验是在以大气为传播介质的条件下进行的,通信质量受环境影响较大,容易产生噪声,为改进通信质量最好采用光纤通信。
A laser communication system is presented,after discussion about the methods and principle of electrooptic modulation?A transferred signal is applied to an electrooptic crystal.The optical modulated signal is received in the receiving end, then demodulated and recovered .The experiment of laser communication shows the realizability of electrooptic modulation in application of laser communication. If it is transfered in the medium of air, the quality of communication will be effected by the environment to be more likely to produce noise .Laser communication is recommended to achieve better communication quality.
