Abstract (en)
[origin: CN106662687A] 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.
