| 1. | Lc apparatus almost meet all the needs of space optical communication such as weight , size , power consume , life , cost , driving voltage , intergration of optics and electricity , programe , optically take ? over aperture , beam scanning , deflexional range and so on . switches , deflexional facilities and scanning equipments which made with lc have been used in the system of labor in space communication . the only bug of lc apparatus is that their answer speed only get microsecond rate or submicrosecond rate . but it is practical for them to be used in special beam capture , scan , deflexion controling which don ’ t concerned with code rate and code type 液晶器件几乎满足空间光通信的所有大的指标要求如重量、尺寸、功耗、寿命、成本、驱动电压、光电集成、可编程性、光学接收孔径、光束扫描和偏转范围等等。液晶光开关、光偏转器、光扫描器已经开始应用于光纤通信的实验系统中。液晶类器件应用于光通信的唯一重大缺陷,是其响应速度目前只能达到微秒级或亚微秒级,不过,在不涉及到码型码率的空间光束捕获、扫描、偏转、控制方面,液晶器件完全可能进入实用化。 |
