Abstract
Method and system for obtaining information about objects in the environment outside of and around a vehicle and preventing collisions involving the vehicle includes directing a laser beam from the vehicle into the environment, receiving from an object in the path of the laser beam a reflection of the laser beam at a location on the vehicle, and analyzing the received laser beam reflections to obtain information about the object from which the laser beam is being reflected. Analysis of the laser beam reflections preferably entails range gating the received laser beam reflections to limit analysis of the received laser beam reflections to only those received from an object within a defined (distance) range such that objects at distances within the range are isolated from surrounding objects.
