宝光现象的研究

Research on Glory Imagery Mechanism

云雾体整体作用形成宝光光环。宝光光环可有多层,其中第二亮带光强最强,形成的宝光光强为Iλ=CαN2r4,是产生宝光的主要光带。宝光光环的直径与云雾幕及观测者之间的距离d和衍射角θ成正比。形成宝光需要在人体与云雾体之间有一定的空间距离,该距离约在 1 .83 ~45. 84m之间,其中 5 ~20m是观赏宝光的适宜距离。

It is believed that the whole fog body can form the glory corona.It contains several light rings,in which the second light is the strongest with the light intensity of I_λ=CαN^2r^4.There exit positive relations between diameter of glory and diffraction angle (θ) and observering distance (d),and a suitable watching distance is approximately 5～20 m.
