| 摘 要： | 介绍了利用恒星测量整层大气透过率的原理和Langley-plot定标方法。研制了整层大气透过率测量系统，系统由望远镜、增强CCD、图像采集卡等组成。利用透过率测量系统测量任意天区1~6等恒星在350~750 nm内分波段弱辐射，对仪器进行定标后计算出夜间整层大气光谱透过率。测量结果与MODTRAN模拟计算结果了比较，证明该大气透过率仪设计是合理的。

| Abstract: | The principle of measuring night-time total atmospheric transmittance with the calibration method of Langley-plot is introduced.Accordingly,a measurement system consisting mainly of a telescope,an intensified CCD,and an imaging data acquiring card has been developed to measure the weak stellar irradiance from level 1 to level 6 during the spectral band of 350~750 nm.The results obtained after calibration have been compared with the simulated value of MODTRAN,which verifies the feasibility of the system's design. |
