Abstract: System and methods for Light Detecting and Ranging (LIDAR) are disclosed. The LIDAR system includes a light source configured to generate a tunable beam, an optical beam steering device positioned to receive at least a portion of the beam and configured to sweep the beam over a range of angles in a field of view (FOV) wherein each discrete frequency of the beam corresponds to a different angle in the FOV, a detector configured to generate an interference signal based on the received portions of the beam, and a processor communicably coupled to the detector. The processor is configured to cause the light source to tune the tunable beam from a first frequency to a second frequency and to calculate a range of an object corresponding to either the first frequency or the second frequency within the FOV.
