Wire grid polarizer with dual absorptive regions

The invention relates to a selectively-absorptive wire grid polarizer. The selectively-absorptive wire grid polarizer (10) comprises an array of parallel, elongated rods (14) disposed over a surface of a transparent substrate (11) with gaps (15) between adjacent rods, each of the rods including a reflective wire (13) sandwiched between two absorptive ribs (12a, 12b). A method of making this wire grid polarizer is also provided. A use of this wire grid polarizer in an image projection system (40) is also provided. 种选择性吸收式线栅偏振器(10)，包括平行的、狭长的条(14)的阵列，该阵列被设置在透明衬底(11)的表面上并且在相邻的条之间具有间隙(15)，所述条中的每个包括夹在两个吸收式肋状物(12a、12b)之间的反射线(13)。种制作所述线栅偏振器的方法。种所述线栅偏振器在图像投影系统(40)中的使用。
