英文摘要: Resonance scattering of sunlight is an effect deduced from a rare atmospheric phenomenon known as solar glory. Its impressive spectral appearance is established by optical interference at precise modulation of the temporal coherence of sunlight within delaylines of microscale water droplets confined by refractive index. A ray-tracing method is used in the study correlated with analysis of the simulated convolution spectrum of backscatter pattern. Resonance modes of low finesse are formed on spectrally isolated intracavity optical paths preventing their destructive interference. The relevant modal wavelengths and diffraction angles are derived for selected temperature and droplet size. Simultaneously, the model explains the alternating polarization of the successive diffraction series.
