透鏡會聚 的英文怎麼說
中文拼音 [tòujìngkuàijù]
透鏡會聚
英文
lens convergence-
It's an easy matter to observe chromatic aberrations, with a thick, simple converging lens.
用一厚的簡單會聚透鏡很容易觀察色差。Analysis showed this might be due to the fact that a black hole passed in front of the star. the gravitation of a black hole can function as a convex lens and focus starlight, resulting in transience increase of apparent brightness of the star
分析顯示，這很可能是因為有一個黑洞在恆星前面經過，黑洞的引力會聚了星光，就像凸透鏡把光線聚焦一樣，使恆星的視亮度增加。When a collimated - well gaussian laser beam passes through a 27i - phase plate and then focused by a lens, a focused hollow beam ( fhb ) will be generated behind the lens, as a result of the completely ( r = 0 ) and partially ( r 0 ) destructive interference effects around the central region of the beam
當一束準直的高斯光束通過具有2位相分佈的位相片和一個薄透鏡時，這將導致在入射高斯光束中心的完全和部分相消干涉效應，於是在透鏡后就會形成一束聚焦中空光束（ fhb ） 。4, single focuse the single head : is single for single laser head that panasonic lead off to adopt to focuse the double the laser beam for focusing ordering the project, he adopting the special whole synthesizing lens, passing lens in the center part ofly the focusing of formation cd the point, and pass the anastigmatic laser beam of part edge the formation the focusing of dvd the point, this kind of construction because of have no the machining to spread to move, and also can t produce the mechanical trouble, therefore increased to recognize the dish the speed, and however and also lowered the cost. but adoption this project of generation is with part of the next generation dvd nonsupports cdr
4單聚焦單鏡頭：為panasonic率先採用的單激光頭單聚焦鏡雙聚焦點方案，他採用特別的全息綜合透鏡，通過透鏡中間部分的激光束形成cd的聚焦點，通過透鏡邊緣部分的激光束形成dvd的聚焦點，這種結構由於沒有機械傳動，也不會產生機械故障，所以提高了認盤速度，不過同時也降低了成本。但採用此方案的第一代和部分第二代dvd不支持cdr 。The laser beams from m - z interferometer will focus on three different dots after going through the positive lens, and the prisms were placed on these dots. owing to the deviation of these prisms, three interferograms will be separated each other when they reach the image board
由干涉儀射出的三束光經凸透鏡會聚于空間位置不同的點，把光楔放置在這些點上可使三束光在空間上彼此分開，利用ccd相機可記錄下三幅干涉圖。Discussions and preliminary experiments are given for some potential applications of left - handed materials. experimental results which are in accordance with expects for the focusing of plane wave using symmetric rings and the focusing of radiate source using rings are obtained. simulation results are also obtained concerning the - like structure based backward radiate antenna and transmission line based left - handed structures
對稱環結構異向介質凹透鏡的平面波聚焦、結構異向介質的點源會聚等實驗都得到了和預期接近的初步結果；對基於結構全固態異向介質後向波介質天線微波異向介質的實驗研究和基於微帶電路結構單元的異向介質進行了計算機模擬研究，也取得了較好的結果。Since these rays do not actually meet, they cannot form an image without a condensing lens of sort.
由於這些光線實際上不相交，如果不用某種會聚透鏡的話，它們是不能成像的。At the fixed laser energy, the results show that the line intensity and stability can be enhanced if the focus of lens is set into the sample
實驗結果顯示在激光能量一定時，對激光束進行會聚的透鏡的焦點在樣品內部時，能提高libs信號的強度和穩定性。分享友人
