中文拼音 [jīngtūtòujìng]
經凸透鏡
英文
planoconvex lens-
A reliable machine shop can cut away a small amout of metal from the aft side of the mounting flange so that the lens will set closer to the film platen.
可以請經驗豐富的機械加工車間從安裝凸緣的後部切削掉少量的金屬,這樣就能使透鏡更加靠近膠片平面。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。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。The interferometric zone plate is the essential of hoes, which is the interference between plane wave and sphere wave, can focus the light beam by diffraction, instead of the way which conventional lens or concave mirrors do
摘要干涉式波帶板系由平面波和球面波兩道光波干涉而成,為研究全像光學元件的基礎,其可經由繞射作用達到聚焦效果,猶如使用傳統凸透鏡或凹面鏡所產生的效果。分享友人
