平流层飞艇光电探测望远镜关键技术分析

Key Technology Analysis of Stratospheric Airship Photoelectric Telescope

介绍了光电望远镜试验平台的研究现状,对地基、天基、机载、气球平台望远镜的性能与特点进行分析和总结。大口径光电望远镜的观测质量受地球大气湍流和大气吸收的影响,有其极限探测能力,而大部分大气扰动发生在大气最底层的对流层。平流层飞艇光电望远镜不受对流层大气扰动的影响,其分辨力可显著提高。在此基础上提出平流层飞艇光电望远镜发展需突破的关键技术,涉及材料、控制、能源、高能物理、光学技术等方面。

Photoelectric telescope platforms on earth, in space, aboard airplanes and balloons are introduced. The performances are analyzed and the characteristics are summarized. Image quality of big aperture telescope is limited by atmospheric turbulence and atmospheric absorption. Most turbulence occurs in the troposphere, the lowest section of the atmosphere. So the angular resolution of stratospheric airship photoelectric telescope could be greatly improved. The key technology of stratospheric airship photoelectric telescope deal with material, control technology, energy sources, high-energy physics, optics, etc.
