    • 1. A rotatable mirror optical switch arrangement (100) comprising: an input array of light sources (160); an output array of light receivers (180); a first rotatable platter (110) of mirror elements arranged between the input array and the output array whereby light (140, 150) from a desired one of the input array of light sources is reflected via the rotatable platter to a desired one of the output array of light receivers dependent on rotation of the first rotatable platter. The mirror elements may be comprised in a free-form surface. The size of a single mirror may be smaller than 1 mm2. A passive optical switch matrix (275) may be positioned between the input and output arrays to increase switching permutations. The mirror elements may be arranged in segments (100), which may be arranged in sectors and rings. This provides the following advantages: lower amount of moveable parts compared with the prior art for same number of optical I/Os; high reliability due to low number of moving parts; mirrors do not move individually (no alignment/recalibration of single mirrors necessary); non-blocking switch; precision built into design.
    • 1.一种可旋转镜光开关装置(100),包括:光源的输入阵列(160); 光接收器的输出阵列(180); 布置在所述输入阵列和所述输出阵列之间的反射镜元件的第一可旋转盘(110),从而来自所述输入光源阵列中的所需一个的光(140,150)经由所述可旋转盘反射到所述输出阵列 取决于第一可旋转盘的旋转的光接收器阵列。 镜元件可以包括在自由曲面中。 单个反射镜的尺寸可能小于1mm 2。 无源光开关矩阵(275)可以​​位于输入和输出阵列之间以增加开关置换。 反射镜元件可以布置成段(100),其可以布置在扇区和环中。这具有以下优点:与现有技术相比,相同数量的光学I / O相比,可移动部件的数量更少; 移动部件数量少,可靠性高; 镜子不单独移动(不需要对齐/重新校准单个镜子); 无阻塞开关; 精密内置设计。
