Improved flash light detection and ranging (also referred to herein as “flash LIDAR”) systems and methods for determining the distance to a target object disposed in a field-of-view. A flash LIDAR system can include an array of illuminators, an array of light detectors, and a signal processor/controller, as well as have a field-of-view in which a target object may be disposed. The flash LIDAR system can effectively divide the field-of-view into a plurality of segments, and each illuminator in the illuminator array can be made to correspond to a specific segment of the field-of-view. The flash LIDAR system can also effectively divide the light detector array into a plurality of subsets of light detectors. Like the respective illuminators in the illuminator array, each subset of light detectors in the light detector array can be made to correspond to a specific segment of the field-of-view.
