Original Abstract Submitted
systems and methods are disclosed to identify a presence of a volumetric medium in an environment associated with a lidar system. in some implementations, the lidar system may emit a light pulse into the environment, receive a return light pulse corresponding to reflection of the emitted light pulse by a surface in the environment, and determine a pulse width of the received light pulse. the lidar system may compare the determined pulse width with a reference pulse width, and determine an amount of pulse elongation of the received light pulse. the lidar system may classify the surface as either an object to be avoided by a vehicle or as air particulates associated with the volumetric medium based, at least in part, on the determined amount of pulse elongation.
