【摘要】 紫台多波段光谱仪近年在Ｈｅ Ⅰ１０８３０ 波区相继研制了一维Ｒｅｔｉｃｏｎ 和ＣＣＤ 相机的探测系统，现又建成了用二个ＣＣＤ 相机能在Ｈｅ Ⅰ１０８３０ 和Ｃａ Ⅱ８５４２／Ｈα同时作两维成像光谱观测的系统。文中简要介绍了它的结构和取得的初步观测结果更多还原

【Abstract】 Several improvements for HeⅠ10830 observation such as the replacement of the detectors, one dimension Reticon and CCD camera, were made on the multichannel solar spectrograph at PMO. Recently a newly developed multichannel infrared imaging system which can work in three wavelength: HeⅠ10830, CaⅡ8542 and Hα is installed. Also given are some preliminary observation results.更多还原
