To provide devices that make a pillar of a vehicle transparent.SOLUTION: A cloaking device includes object-side half Fresnel lenses 100, 140, image-side half Fresnel lenses 120, 160, and a planar reflection boundary 110 positioned between the object-side half Fresnel lenses 100, 140 and the image-side half Fresnel lenses 120, 160. The object-side half Fresnel lenses 100, 140 and the image-side half Fresnel lenses 120, 160 each comprise inward facing surfaces 162, 142 and outward facing Fresnel surfaces 144, 164. The planar reflection boundary 110 comprises an inward facing mirror surface 112. Light from an object that is positioned on the object side and obscured is redirected by the object-side half Fresnel lenses 100, 140, the planar reflection boundary 110 and the image-side half Fresnel lenses 120, 160 to form an image of the object on the image side of the cloaking device, so that the light appears to pass through the cloaked region.SELECTED DRAWING: Figure 1

    【課題】ビークルのピラーを透明にするデバイスを提供する。【解決手段】クローキングデバイスには物体側ハーフフレネルレンズ100,140、画像側ハーフフレネルレンズ120,160、および物体側ハーフフレネルレンズ100,140と画像側ハーフフレネルレンズ120,160の間に位置付けされた平面反射境界110が含まれる。物体側ハーフフレネルレンズ100,140および画像側ハーフフレネルレンズ120,160は各々、内向き表面162,142および外向きフレネル表面144,164を含む。平面反射境界110は内向きミラー表面112を含む。物体側の視認不能化された物体からの光が、物体側ハーフフレネルレンズ100,140、平面反射境界110および画像側ハーフフレネルレンズ120,160により方向転換されてクローキングデバイスの画像側に物体の画像を形成し、被クローキング領域を通過したように見える。【選択図】図1
