Abstract: A Light Detection and Ranging (LiDAR) scanning system, having a window blockage detector, aids in delivering reliable point cloud data associated with surroundings during instances of window blockage. A laser source within the system may generate one or more beams of light transmitted through a window, scanning the surroundings for external objects. The window blockage detector couples to receive scattered light from the window, as well as returning light from an object in the path of one or more light beams. From the scattered and returning light pulses, the window blockage detector having a thresholding method determines a window state relative to a select one of the following states including, unblocked, blocked, and null; wherein the null state exists when the beam of light intersects an empty sky or a highly absorbent object. Thereby, the LiDAR system provide a more accurate picture of a vehicles surrounding.
