结合以大截面光纤传象束作为中继传象元件的光纤望远镜研制，阐述了光纤望远系统的组成和成象原理；提出了为实现系统具有较高的光学性能、良好的传象质量，在设计上应作的考虑和措施，其中包括系统光学参数确定和结构的选择；此外，还讨论了光纤望远系统中的一些特殊问题，如光束限制、调焦及象质改善等。 Combined with the optical fiber telescope with a large cross-section of the optical fiber as the relay image element, the composition and imaging principle of the optical fiber telescope system are expounded. In order to realize the system with high optical performance, good image quality, Considerations and measures should be taken in the design, including the selection of system optical parameters and the choice of structure. In addition, some special problems in optical fiber telescope system such as beam limiting, focusing and image quality improvement are also discussed.
