摘要:

介绍了利用夜晚恒星辐射测量整层大气透过率的仪器及定标方法。基于已有的研究工作基础,利用VisualC++6.0开发和完善了整层大气透过率采集程序,使仪器具有自动采集数据功能。利用整层大气透过率测量仪对不同光谱类型的恒星分别进行了测量定标实验,对测量数据进行了分析和处理,得到了六大类光谱恒星在大气层上界的仪器测量值。基于夜晚整层大气透过率测量多目标定标原理,在完成各大光谱类型的恒星辐射定标测量后,就能进行仪器的实时大气透过率测量。

Abstract:

Total atmospheric transmittance measurement equipment and calibration methods were described. Based on the existing research results, the total atmospheric transmittance collection procedures was developed and improved with Visual C++ 6.0, so that the equipment can automatic collect data. The atmospheric transmittance of stellar spectra with different types were measured using the total atmospheric transmittance measurement equipment, and the measured data were processed and analyzed, and the measurement value for six categories of stellar spectra at the upper bound of atmosphere were obtained. Based on the total atmospheric transmittance multi-objective calibration principle and the completion of calibration measurement for the major stellar spectral types, the equipment is able to carry out the real-time measurement of the total atmospheric transmittance.

Key words: total atmospheric transmittance, multi-objective calibration, spectral type, measurement
