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。 -
With the enlargement of the aperture, the weight of mirror is increased rapidly, which brings a series of technical problems
隨著主鏡口徑的增大，其自重也急劇增加，並由此帶來一系列技術難題。 -
Muti - aperture overlap - scanning technique ( maost ) and target function can solve the problem of testing a large optical surface on the basis of ordinary digital interferometer of wavefront, and get the most information of wavefront in the end in the condition of big kr, muti - aperture overlap - scanning technique ( maost ) using target function is proved and we can get the most information of wavefront in the case of guarantee of high precision by the aid of simulation, experimental and tests, many influential factors, i. e., the apertureconnection mode, shape of mirror, error in subaperture test and kr are analysed contribute to controlling and testing large optical surface
本文首先在較大孔徑放大系數（ 4 ）的情況下，論證了目標函數多孔徑拼接技術，保證了較高的精度，得到較完整的波前信息。然後，結合實驗結果，從拼接模式、被測面形、測量誤差、數字干涉儀解析度和不同孔徑放大系數等角度出發，分析了各種因素對精度的影響，並詳盡的探討了各種誤差源，包括靜態誤差、動態誤差、擬合誤差、拼接誤差。
