偏振光

Based on the Mie scattering theory, a formula to calculate the scattered light flux in a certain solid angle under the condition of polarized light input is derived form the formula for calculating scattered light intensity. The results are compared with the condition illuminated by a unpolarized light.

Apart from this polarizing feature, these glasses serve the same purposes as any dark glasses, absorbing 50% of the incident light; in an unpolarized beam, half the light can be considered as polarized horizontally and half vertically, and only the vertically polarized light is transmitted.

除偏振特色之外，为了同一目的，眼镜可以做成暗色，50%的入射光可以被吸收；在非偏振的入射光，有一半可以认为是水平偏振，另一半认为竖直偏振的。这样仅有竖直偏振光可以传播。

In this paper, several methods are put forward, by which axial resolution of scan microscope could be improved.
