AI总结：
本文简述了Bernard Lyot发明的单色双折射滤光片技术及其改进，重点介绍了基于该技术的H$α$太阳色球望远镜复制品在1958至1994年间于上普罗旺斯观测站的运行能力及其对国际地球物理年太阳活动监测的贡献。
摘要：
Bernard Lyot于1933年发明了单色双折射滤光片，旨在利用Pic du Midi天文台的日冕仪研究日面边缘上方太阳结构的日冕发射。该滤光片随后得到改进，他于1948年在Meudon首次观测了太阳盘面上方的色球层。他去世后，Grenat和Laborde在即将到来的国际地球物理年（IGY 1957-1958）框架内继续了研发工作。一台现代H$α$太阳色球望远镜很快建成，耀斑巡视于1956年开始。该仪器由两家公司（SECASI和OPL）复制，并在全球范围内推广，以致力于IGY太阳活动监测的共同努力。我们在本文简述了其中一台复制品在1958至1994年间于上普罗旺斯观测站的运行能力。
英文摘要：
Bernard Lyot invented the monochromatic birefringent filter in 1933 in order to investigate the coronal emissions of solar structures above the limb with the coronagraph installed at the Pic du Midi observatory. The filter was improved later and he made the first observations of the chromosphere above the solar disk in 1948, at Meudon. After his death, Grenat and Laborde continued the development in the frame of the coming International Geophysical Year (IGY 1957-1958). A modern H$α$ heliograph was completed soon and the flare patrol started in 1956. This instrument was reproduced by two companies (SECASI and OPL) and disseminated around the world in order to contribute to the IGY common effort dedicated to the solar activity survey. We describe in this short paper the capabilities of one of these copies operating at Haute Provence station from 1958 to 1994.
