摘要
本文介绍了一种用于双反射镜光学系统的自动调焦装置,其中包括简要的光学原理、机械示意图,着重介绍电子线路。这种调焦方法稳定可靠,调焦精度高,已实际用于1.56米天体测量望远镜中,效果很好。
An automatic focusing device for the two-mirror optical system is described, including brief optical principle, mechanical schematic diagram and, especially, electronic circuits. This focusing method is steady and reliable successfully with high focusing precision. The device has been successfully used for the 1.66m astrometric telescope.
