Polarization Spectroscopic Studies of Ordered Samples

摘要

In linearly polarized light all electric field vectors have the same direction,called the polarization direction.It is always perpendicular to the direction of the light beam.Light in nature,in particular scattered light,is often partially linearly polarized.Light from the blue sky is scattered light and is thus also partially linearly polarized in a direction that is perpendicular to the plane defined by the point on the blue sky that is being observed,the observer,and the sun (however,a heavy layer of clouds will often eliminate the light polarization from the blue sky).
