The birth of the telescope,aberration and achromatic lenses,traditional reflectors and refractors,Schmidt telescopes,modern giant telescopes,space and moon-based telescopes are successively introduced in the seven parts of this paper.
全文分7个部分,内容包括望远镜的诞生、像差和消色差透镜、传统的反射望远镜和折射望远镜、施密特望远镜的作用、当代巨型望远镜的出现、空间望远镜,以及对月基望远镜的憧憬。
