摘要：
A polarizer structure for a headlight includes an interference-type polarizer followed by an absorption-type polarizer. The interference-type polarizer in one form of the invention is constituted by rectangular plate polarizing sections in a zigzag arrangement, so that the apex angle formed by adjacent polarizing sections is always 90.degree. while the angle of each polarizing section to the optic axis is 45.degree.. In another form of the invention, the polarizer sections are arranged in a diverging louvre arrangement provided with reflecting layers between the polarizing sections, both the polarizing sections and the reflecting layers at an angle of 45.degree. with the optic axis.
