Abstract
A LIDAR system includes a light source configured to output light. A portion of the light is included in a LIDAR signal that travels a LIDAR path from the light source to an object located outside of the LIDAR system and from the object to a filter and from the filter to a processing unit. The processing unit is configured to convert optical signals that include the LIDAR signal to electrical signals. A portion of the light is also included in one or more misdirected signals. Each of the misdirected signals travels a different misdirected path from the light source to the filter. Each of the misdirected paths is a different path from the LIDAR path. The system also includes a filter being configured to filter out the LIDAR signal from the misdirected signals. The system also includes electronics that generate LIDAR data from the electrical signals.
