摘　　要：本文介绍一台口径为50 mm、用于在浮空平台上进行观测的白光日冕仪.工作波段为5500Å,透过带宽为50Å,为传统的Lyot式日冕仪,可观测1.08–1.50个太阳半径范围的内日冕.用鑫图的Dhyana 95V2-YNTT sCMOS相机采集观测数据.对日冕仪进行了三次地面观测实验:第一次在云南丽江高美古观测站进行,另两次在海拔4800 m左右的四川稻城无名山观测站进行,后两次实验获得了较为理想的日冕白光观测数据.与美国高山天文台的20 cm口径K-cor日冕仪在同一天之内观测到的结果基本一致,说明白光日冕仪的研制获得成功.同时获得的天空背景亮度表明,稻城无名山是一处较为理想的高海拔太阳观测址点.A 50-mm balloon-borne white-light coronagraph was introduced in the study,which was a traditional Lyot coronagraph,with a working wavelength of 5500Åand a passband of 50Åfor observing the inner corona from 1.08 R_(⊙)to 1.5 R_(⊙).Dhyana 95V2-YNTT sCMOS was used to collect the observational data.Three experiments were conducted on the ground.The first experiment was conducted at the Gaomeigu Station,Lijiang,Yunnan,and the other two were conducted at the Wumingshan mountain in Daocheng,Sichuan,approximately 4800 m above sea level.The data with scientific significance were obtained in the latter two experiments.Comparison of our data with those obtained by the K-cor of the 20-cm aperture of the High Altitude Observatory at the Mauna Loa Solar Observatory on the same days verified the consistency of the two datasets,indicating the successful development of the white-light coronagraph.The brightness of the background sky indicates that Wumingshan is an ideal high altitude site for solar observations.
