摘要

摘要:为了满足高精度相机在外场环境下的检测要求,采用碳化硅光学材料制作反射镜,碳纤/环氧树脂基复合材料制作遮光筒,设计了一套重量轻、自身精度高、温度稳定性好的离轴平行光管。在二者线胀系数保持二倍关系的情况下,在一定温变范围内保持精度的稳定性。经检测,口径为400 mm,焦距为8 m的离轴平行光管的温变为(2010) ℃,系统波像差为1/5(P-V值,=632.8 nm)和1/27(RMS值),达到了设计要求,能够在外场环境下使用。

Abstract:To meet the testing requirements of high-precision cameras in the outer environment, an off-axis collimator with lightweight, high accuracy, and high temperature stability is designed. Silicon carbide and carbon fiber/epoxy resin matrix composite are adopted to make a reflector and a shading tube respectively for the off-axis aspherical collimator. The collimator can keep accuracy stability in their linear expansion coefficients in a twice at a certain temperature range. After testing, the wavefront aberration of the off-axis collimagor with a diameter of 400 mm and a focal length of 8 m is 1/5(P-V, =632.8 nm) and 1/27(RMS) at a temperature range of (2010) ℃. The collimator can be used in the outer environment.
