【摘要】 红外成像技术以作用距离远、受大气能见度影响小等优点,在靶场测量中得到了广泛的应用。为了降低大口径红外测量电视的加工成本,近年来广泛采用以金属材料作为主、次镜的卡塞格林系统。本文针对金属红外主镜的支撑方式进行了有限元分析和综合比较,选取最佳方案后根据该支撑方式对主镜进行了优化设计,在满足主镜面形精度的前提下进行了轻量化设计,为工程设计提供了理论基础。更多还原

【Abstract】 Infrared imaging technology to the role of distance by the impact of atmospheric visibility advantages,such as that in the range measurement has been widely used.To reduce the large aperture infrared measurement of TV’s processing costs,in recent years,extensive use of metal materials as the primary,secondary mirror of the Cassegrain system.In this paper,metal infrared primary mirror support the way of the finite element analysis and comprehensive comparison,select the best support after the manner according to the optimized design of the primary mirror,mirror shape to meet the precision of the main premise of the lightweight design,for engineering design provides a theoretical basis.更多还原
