f-theta lenses 中文意思是什麼

f-theta lenses 解釋
平場聚焦鏡頭
  • f : 1 【化學】 fluorine 2 【生物學】 （generation of） filial offspring; 【植物；植物學】子代 〈F1 雜...
  • theta : n. 希臘字母表的第八個字母〈相當于英語的th〉。
  • lenses : 鏡頭
  1. The design results and the performance evaluation of f - theta200 and f - theta500 are given in detail. the designed lenses are simple and compact and their cost are low. the focusing performances are within diffraction limit, the relative illuminations quite uniform and the distortion relative to the f - theta linear relation small

    詳細給出了f - theta200和f - theta500的像質評價和研製結果，所研製的f - theta鏡頭具有工作面積大、結構簡單緊湊、加工成本較低、聚焦性能達到衍射極限、工作面上相對照度分佈均勻、能量集中度高和畸變小等優點。
  2. Secondly, the initial structure parameters of the f - theta lens are obtained with p - w method. and then a few of optimal f - theta lenses with different working area and required optical performances are gained with zemax optical design software under practical constrained conditions

    結合實際使用時的具體要求，如工作面為平面、工作面上照度須均勻分佈等，利用zemax光學設計軟體，建立合理的品質函數，優化設計得到多種不同工作面積的f - theta鏡頭。
