1. A method of operating a LIDAR system, comprising:
causing the LIDAR system to output a system output signal that can be reflected by an object located outside of the LIDAR system, the object being made of a material;
determining a value of a signal level ratio, the value of the signal level ratio being different for different materials; and
identifying the material from the value of the signal level ratio.
