Abstract
In one embodiment a LIDAR generates high-intensity laser pulses with intensities above a threshold intensity (e.g. above an eye-safe intensity) in a 2-D angular range in a field of view. The LIDAR further generates low-intensity (e.g. eye-safe) laser pulses in a protective guard region (e.g. a guard ring) that surrounds the high-intensity laser pulses. In response to detecting an aspect of an object using reflections from the low-intensity laser pulses (e.g. a person on a trajectory that will intersect the high-intensity laser pulses) the LIDAR modifies the angular range of subsequent high-intensity laser pulses. In this way the LIDAR can adapt or steer the angular range of the high-intensity laser pulses to avoid an object detected within the low-intensity guard region.
