  1. The unfocused aspherical surface system is one of the main structure of large emiting system. in the system, the more large the relative aperture of primary mirror, the more small the focal length and the tube of system, and the more light the weigth

    這個系統中的主反射鏡的相對孔徑越大,其焦距就越短,相應地系統筒長就越短,重量就越輕,這樣就越能滿足車載或機載系統的實戰要求。
  2. This paper is a part of the project : research of manufacturing technology for unfocused aspherical surface system of large relative aperture, sponsored by national high technology 863 - 802. the purpose of this paper is deeply research the testing methods of primary and second mirror for unfocused aspherical surface, and to present the testing methods of primary mirror of the large relative aperture and transmission and reflected second mirror. the beam path diagrams and the relative design results are given in this paper

    本文是國家高技術項目863 - 802的子課題「大相對孔徑無焦非球面系統製造技術研究」的一部分,其目的是對大相對孔徑無焦非球面系統的主鏡和次鏡檢驗方法進行深入研究,提出大相對孔徑主鏡和透射式及反射式次鏡檢驗方法,並給出檢驗方案和相關的設計結果。
  3. In this paper, we brought forward an innovative idea : according to the characteristics of easy deformation of ultra - thin mirror, we employ a sphere mirror, which is easier to fabricate and test, to replace the aspherical mirror, then the sphere mirror is deformed into an aspherical one by active optics technology. on this purpose, we need to study the mechanism and method of shaping a spherical mirror into an aspherical one

    由於非球面鏡的加工和檢測都比較困難,因此本文提出了一個大膽的設想:利用超薄鏡易於變形的特點,以加工和檢測難度遠低於非球面的球面來代替非球面,運用鏡面的主動控制技術將球面反射鏡變形成所需精度的非球面反射鏡。
  4. The mathematic model of the ultra - thin spherical mirror is to be treated as elastic thin shell. then the predigested model, i. e., bended beam, used in qualitative analysis was proposed, and its deflection and stress formulas under the freely supported condition were set up. based on an off - axis aspherical primary mirror, the relationship of aspherical surface error ( rms ) in tangential plane with bended beam ’ s radius r, position s of concentrated load p and geometry length l of arc was analyzed

    根據這一設想,本文建立了超薄鏡的數學模型?薄殼,並提出了強制力作用下超薄鏡的簡化模型?曲梁,推導了曲梁在簡支情況下受力變形的撓度公式,並結合一個實例,計算出曲梁變形后與所需非球面的面形殘差( rms )在子午方向與曲梁弧長l 、曲梁半徑r及集中力位置s的關系及滿足面形精度的r和s范圍,分析了弧矢方向的rms ,得出了同時滿足子午和弧矢方向面形要求的l 、 r和p 。
  5. Manufacturing of large aspherical primary mirror is one of the key technologies for optics

    大口徑非球面主鏡的加工是光學製造里的關鍵技術之一。
  6. The projection optics with aspherical mirror of sub - nanometer accuracy are required to get a resolution of less than 0. 1 m m and wide exposure area simultaneously. the precision of polishing and testing for such ashperical surface is fairly high and it has not been achieved yet in our current state

    Euvl微縮投影物鏡為了同時實現大的曝光視場和0 . 1 m以下的成像解析度,微縮投影光學系統需採用面形精度達亞納米量級的非球面,但我們現階段的光學加工和檢測技術距此要求尚有一定的差距。
