1. A LIDAR system, comprising:
at least one light source configured to project laser light toward a field of view of the LIDAR system;
at least one sensor configured to detect laser light reflections from objects in the field of view of the LIDAR system; and
at least one processor configured to:
use the laser light reflections to generate point-cloud representations of an environment of the LIDAR system within the field of view of the LIDAR system,
output navigational information based on the generated point-cloud representations to one or more processors associated with a vehicle on which the LIDAR system is mounted,
store at least some of the generated point-cloud representations in a memory to provide a point-cloud archive,
detect occurrence of a point-cloud archive output triggering event,
in response to detection of the point-cloud archive output triggering event, collect from the memory two or more point-clouds from the point-cloud archive that were generated within a predetermined period of time relative to the detected point-cloud archive output triggering event, and
output the two or more point-clouds collected from the memory.
