光谱滤波装置在白天测星中的应用

Application of Spectral. Filter Device in Measuring stellar in Daytime

概述了天空背景光、星体及探测器件ＣＣＤ的光谱特性，并根据这些特性，采用光谱滤波装置，提高星光与天空背景光的对比度，从而提高白天测星等的能力。

This paper summarizes the spectral characteristics of atmosphere and stellar as well asdetector CCD. In accordance with the spectral characteristics we have adopted the filter device to increase the contrast of stellar to the sky background,thus the ability for measuringstellar is evidently improved in daytime.
