The mechanical design of the 85 cm telescope tube

φ85厘米望远镜镜筒的机械设计

During 1982 to 1984, the LEST Foundation finished the possibility research, made a conceptional telescope design, carried out the experiments of helium filling and wind tunnel testing for the telescope tube and suggested a detailed financial budget with a total amount of 25 million US dollars.

自1982年到1984年，LEST基金会完成了可行性研究、方案设计，做了镜筒充氦和风洞试验，并提出了一个总额为2500万美元的财政预算。

Resonant Frequency and Altitude Bearing of the Optical Tracking Telescope Tube

Under this condition, the stray light of a Cassegrain telescope comes from diffuse reflection of telescope tube wall, directly reflected light by a horseshoe mirror, diffuse reflection light by secondary mirror mount and is symmetrically distributed.

在这种条件下，卡塞格伦望远镜系统杂散光成对称分布，主要来源于望远镜筒壁的漫反射光、马蹄镜的直接反射光和次镜支架的漫反射光。
