http://www.uwgb.edu/dutchs/PETROLGY/GENLIGHT.HTMAlthough we often speak of "unpolarized" light, every photon of light is polarized in some manner. "Unpolarized" light is a random mixture of light of all polarizations. When light has an easily observed dominant polarization, we refer to it as polarized.
注意这里讲的是"每个光子都是偏振的,"而不是象007所说"所有光都是偏振的。"
