mirror axis 中文意思是什麼
mirror axis
解釋
鏡像軸；鏡像對稱軸；鏡像軸向-
The optical manufacturing for off - axis aspheric mirrors has become increasingly challenging for two reasons. the mirrors, in addition to being larger, are more aspheric and off - axis in order to meet the requirement of next generation space camera, which is commonly configured as three - mirror - anastigmat ( tma ) to get both wide fov and high resolution, and the required accuracy is more stringent
近年來，人們提出了「離軸三反消像散」 （ tma ）結構來滿足下一代空間相機「詳查」和「寬覆蓋」的技術要求，該結構中要求使用三塊離軸非球面反射鏡，而大口徑、高精度離軸非球面反射鏡的製造技術是研製tma結構空間相機的主要技術瓶頸之一。 -
The mirror of an astronomical telescope forms at its focal point an image of a star on the axis of the mirror.
天文望遠鏡把在鏡軸上的星體成象在焦點上。 -
The symmetric values about the imaginary axis of zero - poles which the unstable process lies in the open and closed right - half plane are defined as their mirror - injection
非穩定過程在開右半平面的零極點關于虛軸的對稱值稱為該零極點的鏡像映射。 -
Off - axis parabolic mirror
離軸拋物面反射鏡 -
Asm 1. 0 contains the entire ccos process, including best - fit sphere calculating, profiler test and anslysis, virtual grinding and polishing, cnc grinding and polishing, etc. as results, the manufacturing process of a f / 1. 17, 770mm x 200mm rectangular even high order off - axis aspheric mirror is presented as an example in detail
最後，比較詳細地介紹了770mm 200mm ， f 1 . 17高次離軸非球面反射鏡的加工、檢驗過程，加工后200mm口徑范圍內加工精度達到0 . 013 rms ，完全滿足了設計要求。 -
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 。 -
Off - axis elliptical mirror
離軸橢圓鏡 -
Off - axis ellipsoidal mirror
離軸橢球鏡 -
Like the primary mirror, the eyepiece has an optical axis, and this axis should be aimed at the center of the main mirror for best performance ? though in practice it is the center axis of the focuser drawtube that you aim at the primary mirror
目鏡和主鏡一樣也有光軸，光軸應該對準主鏡的中心? ?盡管實際上，目鏡的光軸對準的是調焦筒（相當于調焦座）的中心。 -
Step 2 : here you adjust the tilt of the secondary mirror to aim the focuser ' s axis at the center of the primary
現在你已經調整了副鏡的傾斜程度，把調焦座的中軸已經對準了主鏡。
