Paper Abstract

How to see the stars in daytime? A new idea is described here in this paper which uses a combination of two methods: one is traditional spectral filtering method and the other is a new attempt on daytime star detection--polarization method. Each of these two method's principle of work, scope of application and limitation on daytime star detection are introduced in detail; and the advantage of the combination is discussed accordingly. Based on the demand of the daytime star detection, a device is designed and its optical system and mechanical structure are also analyzed in this paper. At last, a further discussion of the existing problems and the possible improvements of the current device are presented.
