| 摘 要： | 以目前技术最为成熟、应用最为广泛的强度调制/直接检测(IM/DD)体制的自由空间激光通信体制为例,利用自主研发的无线激光通信系统,采用漫反射的方法,研究了小功率脉冲激光对自由空间激光通信的干扰效果。利用不同调制频率、不同脉宽的半导体激光器和固体激光器分别进行了多次激光干扰实验,证明了干扰的可行性,得出了调制频率、脉宽与干扰效果的关系,并结合自由空间激光通信原理和通信设备的工作流程对实验现象加以解释和分析,提出了低功率脉冲激光对通信系统实现干扰的条件。 |

| Abstract: | The free space optical communication(FSO) based on IM/DD is the most mature technology and widely used recently.The way that how the low power pulse infrared laser jammed the FSO system which was developed independently based on IM/DD was researched.To approach the reality jamming application,laser was diffused by a white paper which was placed out of the FSO′s field of view.Amount of experiments were carried out by using laser diode and diode-pumped solid-state laser(DPL) with different repetition rates and different pulse widthes.The results show that the FSO based on IM/DD can be jammed by a low-power infrared laser,and the relationship between the efficiency of jamming and the parameters of jamming laser such as repetition rate and pulse width is gained.Moreover,the experiment phenomena is explained by using theoretical analysis,concluded the conditions of the FSO jamming by low power and pulse infrared laser. |
