光谱望远镜分辨本领测量方法及初步结果

Measurement Method and Preliminary Result of the Spectral Resolution for the Solar Spectral Telescope

介绍了云南天文台太阳光谱望远镜分辨本领的照相测量方法,给出了初步测量结果为100500,这一结果与它的可达到值300000相差较大。对产生的原因进行了分析讨论,认为主要是目前光谱望远镜的光学系统尚未处在正常工作状态。

A measurement method of spectral resolution is given in this paper for the Vacuum So- lar Spectral Telescope(VSST)at Yunnan Observatory.A preliminary result measured is ob- tained photographically.The value obtained is much less than that to be able to reach for the VSST.The reasons of making the big difference are discussed.The most important reason is that the optical system of the VSST is at present out of a normal state.
