LONG-RANGE LiDAR

Disclosed herein are light detection and ranging (LiDAR) systems. In some embodiments, a LiDAR system comprises a plurality of N illuminators, each of the plurality of N illuminators configured to illuminate a respective one of a plurality of N illuminator fields-of-view (FOVs); a detector comprising at least one focusing component and at least one detector array, wherein the detector is configured to observe a detector FOV that overlaps at least a first illuminator FOV of the plurality of N illuminator FOVs; and at least one processor configured to cause a first illuminator of the plurality of N illuminators to emit an optical pulse to illuminate the first illuminator FOV, obtain a signal representing at least one reflected optical pulse detected by the detector, and determine a position of at least one target using the signal. In some embodiments, a LiDAR system comprises a plurality of illuminators, including a first illuminator configured to illuminate a first illuminator field-of-view (FOV), and a second illuminator configured to illuminate a second illuminator FOV; a plurality of detectors, including a first detector comprising a first focusing component and a first detector array, wherein the first detector is configured to observe at least a portion of the first illuminator FOV, and a second detector comprising a second focusing component and a second detector array, wherein the second detector is configured to observe at least a portion of the second illuminator FOV; and at least one processor configured to cause the first illuminator to emit a first optical pulse to illuminate the first illuminator FOV, cause the second illuminator to emit a second optical pulse to illuminate the second illuminator FOV, obtain at least one signal representing at least one reflected optical pulse detected by the first detector or the second detector, and determine a position of at least one target using the at least one signal.
