    Abstract: An optical switch is described having mirrors that are located over an area having an approximate oval shape. Each mirror is pivotable about a first axis and about a second axis transverse to the first axis. Because of the construction and assembly of each mirror, pivoting about the first axis is more limited than pivoting about the second axis. The area over which the mirrors are located is designed to accommodate pivoting about the first axis and about the second axis such that the area has a length and a width wherein the length is much more than the width. In addition, pivoting about the first axis limits pivoting about the second axis and pivoting about the second axis limits pivoting about the first axis. Because pivoting about one axis limits pivoting about another axis, the area over which the mirrors are located has an oval shape as opposed to a rectangular shape.

    Abstract translation: 光学开关被描述为具有位于具有近似椭圆形的区域上的反射镜。 每个反射镜可围绕第一轴线和横向于第一轴线的约第二轴线枢转。 由于每个反射镜的构造和组装,围绕第一轴线的枢转比围绕第二轴线枢转更受限制。 反射镜所在的区域被设计成容纳围绕第一轴线和围绕第二轴线枢转,使得该区域具有长度和宽度,其中长度远远大于宽度。 此外,围绕第一轴线的枢转限制围绕第二轴线枢转并围绕第二轴线枢转限制绕第一轴线枢转。 由于围绕一个轴线枢转限制围绕另一个轴线的枢转,所以反射镜所在的区域具有与矩形形状相反的椭圆形形状。
