    • An active faceted mirror system is disclosed. The active faceted mirror system includes a set of active facet mirror devices, a base plate and a set of pins for mounting the active facet mirror devices to the base plate. Each of the active facet mirror devices includes a mirror substrate with a reflective surface and a bearing hole on the reverse side for mounting. Additionally, each of the active facet mirror devices includes at least three actuator targets located on the back side of the mirror substrate, a jewel bearing and a flexure for supporting the mirror substrate. The base plate includes a series of bearing holes for mounting the active facet mirror devices and at least three actuators for each of the active facet mirror devices. A set of facet controllers located on the base plate can be used to control the positioning of the active facet mirror devices to produce a desired illumination effect.
    • 公开了一种主动刻面镜系统。 主动分面镜系统包括一组主动分面镜装置,底板和一组用于将活动小面镜装置安装到基板的销。 每个活性刻面镜装置包括具有反射表面的反射镜基板和用于安装的反面上的轴承孔。 此外,每个活动刻面镜装置包括位于镜基板背面的至少三个致动器目标,宝石轴承和用于支撑镜面基板的挠曲件。 基板包括用于安装主动分面镜装置的一系列轴承孔和用于每个主动分面镜装置的至少三个致动器。 可以使用位于基板上的一组小面控制器来控制活动小面镜装置的定位以产生期望的照明效果。
