Description
第１図は、ヘッドライト側に装着する偏光フィルターの
概念図。第２図は、フロントガラス側に装着する偏光フ
ィルターの概念図。
第１図中イは、ライトを発光する側の車両。ａは、車両
イのライトの縦波光。ｂは、車両イのライトの横波光。
Ａは、偏光フィルター（縦波通過用）。ａ′は、偏光フ
ィルター通過後の光。第２図中口は、車両イの対向車両
。Ｂは、偏光フィルター（横波通過用）。Figure 1 is a conceptual diagram of a polarizing filter installed on the headlight side. Figure 2 is a conceptual diagram of a polarizing filter attached to the windshield. A in Figure 1 is the vehicle that emits the light. a is longitudinal wave light from the lights of vehicle A. b is the transverse wave light from the headlights of vehicle A. A is a polarizing filter (for passing longitudinal waves). a' is light after passing through a polarizing filter. The middle entrance in Figure 2 is the oncoming vehicle of vehicle A. B is a polarizing filter (for passing transverse waves).
