空间低温光学的新进展

The new development of space cryogenic optics

介绍美国计划于２００２年发射的新型红外太空望远镜的低温系统、低温光学仪器的性能；主镜和二次镜的低温性能试验和材料的选择。概述了９０年代初期发射的哈勃太空望远镜在实际运转时所存在的问题。

This article introduces the properties of cryogenic system and cryogenic optical instruments in new type of infrared space telescope which the United States projects to send in 2002; the choice of cryogenic property experiments and materials of major mirror and secondaly mirror. It summaries the problem of Hubble space telescope during practical revolvting which has been sent in early nineties.
