白天用CCD摄象机对天体目标的探测及实验

Detection of Celestial Objects by CCD Camera in the Daytime and the Related Experiments

文中介绍了用ＣＣＤ摄象机及相应的光学系统对天体目标的探测能力计算及白天用ＣＣＤ摄象机对天体目标的探测实验。给出了计算被测天体目标星等的计算表达式，指出白天在天空背景亮度在１２００ｃｄ／ｍ~２至２７００ｃｄ／ｍ~２时用普通低照度ＣＣＤ摄象机与大口径天文望远镜配合可探测到４至４．

The calculation of the detecting capability for the celestial objects with CCD camera and the corresponding optical system,and the detecting experiments of celestial objects with CCD camera in the daytime are presented in the paper. The expressions for calculating the magnitude of the measured celestial objects ar- given.4-4. 6m stars can be measured in the daytime by the common low illuminance CCD camera and large aperture astronomical telescope when the sky birghtness within 1200 cd/m2 to 2700 cd/m2.
