Abstract
A system and method of LIDAR imaging to overcome scattering effects pulses a scene with light pulse sequences from a light source. Reflected light from the scene is measured for each light pulse to form a sequence of time-resolved signals. Time-resolved contrast is calculated for each location in a scene. A three-dimensional map or image of the scene is created from the time-resolved contrasts. The three-dimensional map is then utilized to affect operation of a vehicle.
