    • A beam-steering apparatus includes a set of planar tiltable mirrors positioned to define a light beam path therebetween. The set of planar tiltable mirrors may incldue from three to five planar tiltable mirrors. Each of the planar tiltable mirrors has a center of rotation lying in a plane of the mirror and each of the planar tiltable mirrors is tiltable about one axis of rotation or two orthogonal axes of rotation that lie in the plane of the mirror. The total number of axes of rotation about which the planar tiltable mirrors of the set of planar tiltable mirrors can tilt is at least five. A mirror drive system tilts each respective planar mirror about its respective axis of rotation or axes of rotation. With this apparatus, an input or output light beam path is steerable over two angular, one rotational, and two lateral-position degrees of freedom.
    • 波束控制设备包括一组平面可倾斜的镜子,其定位成在其间限定光束路径。 这组平面可倾斜的镜子可以包含三至五个平面可倾斜的镜子。 每个平面可倾斜反射镜具有位于反射镜平面中的旋转中心,并且每个平面可倾斜反射镜可围绕位于反射镜平面内的一个旋转轴线或两个正交旋转轴线倾斜。 该组平面可倾斜镜子的平面可倾斜镜子可以倾斜的旋转轴线总数至少为5。 反射镜驱动系统围绕其各自的旋转轴线或旋转轴线倾斜每个相应的平面反射镜。 利用该设备,输入或输出光束路径可在两个角度,一个旋转和两个横向位置自由度上操纵。
