optical beam scanning 中文意思是什麼
optical beam scanning
解釋
光束掃描-
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。 -
The super resolution effect of sb layer super resolution structure is also investigated with near - field scanning optical microscope. in addition, a rigorous three - dimensional ( 3d ) optical electromagnetic finite - difference time - domain ( fdtd ) model for analysis of a sil system is detailed. in order to accurately analyse sil model, a new method of setting a focused gaussian beam source in fdtd grids is presented
此外，本文還建立了對sil系統光傳輸特性進行模擬的時域有限差分程序，提出一種在fdtd模擬的離散空間設置會聚高斯光源的新方法，並模擬了會聚高斯光束在sil系統中的傳輸，研究了sil在不同離焦情況下底面出射光場幅度及光束半徑的變化規律，為sil存儲系統的優化設計提供了理論依據。 -
Some electro - optical crystals can result in birefringency when they are pressed by electric field, by controlling the intensity of the electric field, we can change the phase of the output optical beam, so the desired scanning direction can be got
它主要是利用某些電光晶體在電場的作用下，可以產生雙折射的原理，通過控制加在光學相控陣中各相控單元兩極間的電場強度，可以改變出射光的相位，從而得到所需角度的掃描。 -
