Abstract
Various methods and systems are disclosed to reduce the false alarm in a lidars having a lidar window surrounding the lidar system, by increasing the propagation loss for a portion of incident light that propagates within the thickness of the lidar window and may be guided toward the detection system of the lidar via an indirect path. Alternatively, or in addition, the shape of the lidar window may be tailored to direct the portion of incident light that propagates within the thickness of the lidar window away from the lidar detection system.
