Device for enhancing the linear polarization intensity of light which passes through a polarizer

摘要

A device for enhancing the linear polarization intensity of light which passes through a polarizer is provided, which comprises: a prepolarizer receiving incident natural light and splitting the natural light into a plurality of polarized light beams with different polarization directions, changing the polarization direction of the light beams, thereby enhancing the light intensity of a particular polarization direction; and a polarizer having polarization direction the same as that of the prepolarizer, receiving the light emitted from the prepolarizer, and then converting the light into a linearly polarized light.
