我们提出了一种薄片结构设计，它使入射光线的方向绕任意但局部的旋转轴旋转任意角度。薄片结构由两个不同的平行多棱镜薄片组成，每个薄片相对于不同的镜面反射光线方向。它们共同导致入射光线围绕不同镜面相交的方向旋转任意角度。我们用使用渲染光线跟踪软件计算的图像和电影来说明这种薄片结构的一些属性。
We present a sheet-structure design which rotates the direction of incident light rays by an arbitrary angle around an arbitrary, but local, rotation axis. The sheet structure consists of two different parallel Dove-prism sheets, each of which mirrors the light-ray direction with respect to different mirror planes. Together, they result in a rotation of the incident light ray by an arbitrary angle around the direction in which the different mirror planes intersect. We illustrate some of the properties of this sheet structure with images and movies calculated using rendering ray-tracing software.
