【摘要】自由空间光通信(FSO)是以大气为传输媒介, 以激光的波长作为载体用以携带高速信息的无线传输技术,它
是光通信与无线通信的结合,并兼有光纤通信的高速传输与无线通信可灵活移动等优点,无须挖沟,无须申请频率许可证,为当
今卫星通信技术的首选。关键技术主要对 FSO 通信系统中接收灵敏度进行分析以及对接收的光学系统中跟踪原理进行剖析,
为进一步提高自由空间光通信的性能作铺垫。
【关键词】自由空间光通信;卫星通信;ATP 中的捕获与跟踪;接收灵敏度的分析

【Abstract】Free space munication, with the atmosphere as the media and the laser’s waveform
as the information carrier, is a wireless transmission technique that can load the high speed information. It
integrates the munication and the munication, and has both the fiber’s high-spend
transfer and the wireless’s flexibility. It is the first choice for modern munication because
unnecessary to bury the cable and apply for a license. The key technology is to analyze the receive sensitivity
of the free space munication system and the tracking principle of the receive optical system, thus
laying a foundation for the future development of free space munication system.
