Example embodiments relate to LIDAR systems with multi-faceted mirrors. An example embodiment includes a LIDAR system. The system includes a multi-faceted mirror that includes a plurality of reflective facets, which rotates about a first rotational axis. The system also includes a light emitter configured to emit a light signal toward one or more regions of a scene. Further, the system includes a light detector configured to detect a reflected light signal. In addition, the system includes an optical window positioned between the multi-faceted mirror and the one or more regions of the scene such that light reflected from one or more of the reflective facets is transmitted through the optical window. The optical window is positioned such that the optical window is non-perpendicular to the direction toward which the light emitted along the optical axis is directed for all angles of the multi-faceted mirror. 示例实施例涉及具有多面镜的LIDAR系统。一示例实施例包括一种LIDAR系统。该系统包括多面镜，所述多面镜包括围绕第一旋转轴线旋转的多个反射面。该系统还包括配置为向场景的一个或多个区域发射光信号的光发射器。此外
