| 摘 要： | 本文阐述了空间光学遥感器中主镜轻量化的必要性．对双凹、平背、单拱和双拱4种形状主镜在重力载荷下的变形进行了分析计算，得出了背部3点支撑方式下双凹主镜最优的结论，并进一步研究了3点支撑的双凹主镜面形变化RMS值随规一化支撑半径r／R的变化规律．

| Abstract: | The necessity of using lightweight primary mirror in spatial optical remote sensor is statal in this paper. The suffoce figure of primary mirrors in shapes of double-concave,plain-rear, single-arch and double-areh is computal, Which works out a conclusion that double-concave mirror is the best one, supported in three-point pattern The regularity of wave front error (RMS value) vs. normalized radius r / R is studied, which indicates that the best support radius is 0.74 |
