  1. This work mainly studies the application of a kind of polymer gradient refractive index ( grin ) micro - sphere - lens fabricated by suspension diffusion co - polymerization method on retro - reflection materials
    本工作研究的是具有梯度折射率( gradientrefractiveindex ， grin )分布的聚合物微球在回歸反射材料上的應(yīng)用。
  2. The digital oral endoscope is designed and realized in this paper , which is based on the technologies of digital signal processing and database , by using gradient refractive index rod lens , that is grin - lens , and photo - electronic imaging device
    摘要以梯度折射率透鏡（自聚焦透鏡）為攝像鏡頭，通過光電轉(zhuǎn)換，結(jié)合數(shù)字信號處理和數(shù)據(jù)庫技術(shù)，設(shè)計并實現(xiàn)了數(shù)字化口腔內(nèi)窺鏡。
  3. Compared with current instruments , the setup can decrease disturbance of disorder radiation by using double layer refractive index sample matching vessel , and it can increase collecting and transmitting efficiency of radiation by adopting single mode fiber with gradient refractive index lens . with a low power laser , the sample has a low scathe , and the laser and the measurement system can be integrated conveniently
    與現(xiàn)有的同類型儀器相比，該儀器采用雙層折射率樣品匹配池減少了雜散光的干擾；采用帶梯度折射率透鏡的單模光纖接收、傳輸散射光信號提高了散射光的收集傳輸效率；用低強度的激光避免了對樣品的輻射損傷，同時可以使激光器和系統(tǒng)集成在一起，整個系統(tǒng)小型實用。
  4. The physical meaning for each of the term in the coupling coefficient is stated . in particular , we advance firstly ( as far as our knowledge ) , that the birefringence can cause additional coupling for the directional coupler . then , taking the ti - diffused linbo3 directional coupler and the ti - diffused linbo3 with gradient refractive index for examples , we make the numerical simulation for the coupling coefficient or the propagation constant , which prove that the birefringence has played a crucial effect on the propagation constant and the coupling between the modes that we can not neglect
    第二，我們推導(dǎo)出了弱導(dǎo)近似下各向異性光波導(dǎo)在任意微擾下的非正交耦合模理論，得到了物理意義鮮明的耦合波方程和耦合系數(shù)表達式，指明了耦合系數(shù)所包含的四項各自的物理意義及在不同條件下的取舍，首次提出在方向耦合器中雙折射將引起附加的耦合，并以鈦擴散鈮酸鋰方向耦合器和折射率漸變分布的鈦擴散鈮酸鋰矩形波導(dǎo)為例對耦合系數(shù)進行了數(shù)值模擬，充分體現(xiàn)了雙折射項對傳播常數(shù)的影響。
