Abstract
There is provided a method for optically scanning a region according to a plurality of scanning directions, comprising: receiving an interleave sequence defining a scanning order for the plurality of scanning directions; sequentially propagating optical pulses according to the interleave sequence; detecting pulse echoes corresponding to a reflection of the propagated optical pulses on at least one object present within the region; and outputting the detected pulse echoes. There is further described a computer-implemented method for correcting a temporal slippage of an optical echo.
