  1. 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

    與現有的同類型儀器相比，該儀器採用雙層折射率樣品匹配池減少了雜散光的干擾；採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集成在一起，整個系統小型實用。
  2. Thus, a telescope with larger collecting area, which usually means larger main mirror or lens, is more powerful. this is the main reason why we prefer large telescopes. large telescopes also improve the

    由於望遠鏡主鏡口徑越大，便意味著它的集光能力越強，即它的能力亦越強，難怪天文學家都是以大為美的傢伙。
  3. This paper presents a type of image measurement and analysis system based on ccd plane array camera and general lens that can accomplish auto - focusing and collecting image and measuring and analyzing on - line assembly - gap of columned work - piece

    本論文在一般光學鏡頭的基礎上實現了一種基於面陣ccd攝像機的圖象測量及分析系統。該系統能夠實現自動對焦採集圖象和在線對回轉體工件裝配間隙進行測量分析的任務。
  4. If you have knowledge in simple image processing, you may reduce the noise further by taking many exposure on the same object, and stack them together in computer. after gaining some experience, you many want to take close - up photos of clusters and nebula. since the magnifying and light collecting power of the camera lens is not enough, you have to connect the camera to a telescope

    在1868年，法國天文學家pierre janssen發現了在太陽的光譜中，有一條奇怪的光譜線，起初科學家以為這是一種地球上並不存在的物質所造成的，所以把這種新物質命名為氦英文為helium ，這個字來自希臘語的helio ，意思即為太陽。
