A LIDAR having dynamic alignment capabilities, the LIDAR may include an optical unit that comprises a sensing unit, a processor and a compensation unit. The sensing unit may include a sensing array that comprises sets of sensing elements that are configured to sense reflected light impinging on sensing regions of the sets of sensing elements of the sensing array, during one or more sensing periods; wherein the sensing unit is configured to generate detection signals by the sensing elements of the sensing array. The processor may be configured to determine, based on at least some of the detection signals, one or more optical unit misalignments related to the optical unit of the LIDAR. The compensation unit may be configured to compensate for the one or more optical unit misalignment.
