PROBLEM TO BE SOLVED: To provide a head-up display system that suppresses double images from a combiner by eliminating or reducing a reflection of a refracted image from the back surface of the combiner.SOLUTION: A combiner 204 includes a polarizing layer 205 having a tilted axis 209. For a uniaxial absorbing axis within this combiner 204, no light with a propagation direction substantially aligned with the tilted axis 209 is absorbed. The tilted axis 209 is oriented at a non-zero angle with respect to the plane of the polarizing layer 205. A refracted ray 214 from a polarized image generation system 201 can have a portion of its light polarized along the tilted axis 209, and the electric field is not orthogonal to the tilted axis 209 and is thereby attenuated by the tilted axis 209.SELECTED DRAWING: Figure 2

    【課題】コンバイナの背面からの屈折画像の反射を除去・低減することによってコンバイナからの二重像を抑制するヘッドアップディスプレイシステムを提供する。【解決手段】コンバイナ204は傾斜軸209を有する偏光層205を含む。このコンバイナ204内の一軸性吸収軸に対しては、傾斜軸209と実質的に揃った伝搬方向を持つどんな光も吸収されない。傾斜軸209は、偏光層205の面に対して非ゼロの角度に向けられている。偏光画像発生システム201からの屈折光線214は、その光の一部分を傾斜軸209に沿って偏光させることが可能であり、電界は傾斜軸209に直交ではなく、傾斜軸209によって減衰させられる。【選択図】図2
