Abstract
A LIDAR system is provided. The LIDAR system comprises at least one processor configured to: control at least one light source in a manner enabling light flux to vary over a scan of a field of view using light from the at least one light source; control at least one light deflector to deflect light from the at least one light source; use first detected reflections associated with a scan of a first portion of the field of view to determine an existence of a first object in the first portion at a first distance; determine an absence of objects in a second portion of the field of view at the first distance; alter a light source parameter; and use second detected reflections in the second portion of the field of view to determine an existence of a second object at a second distance greater than the first distance.
