scan aperture 中文意思是什麼
scan aperture
解釋
掃描孔徑-
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
液晶器件幾乎滿足空間光通信的所有大的指標要求如重量、尺寸、功耗、壽命、成本、驅動電壓、光電集成、可編程性、光學接收孔徑、光束掃描和偏轉范圍等等。液晶光開關、光偏轉器、光掃描器已經開始應用於光纖通信的實驗系統中。液晶類器件應用於光通信的唯一重大缺陷，是其響應速度目前只能達到微秒級或亞微秒級，不過，在不涉及到碼型碼率的空間光束捕獲、掃描、偏轉、控制方面，液晶器件完全可能進入實用化。 -
