Abstract
An optical device provided by the present invention can comprise: a light separating unit receiving one first beam so as to output k (k is a natural number) second beams; a light steering unit changing the k second beams up to a first steering angle, so as to output a third beam; a lens unit receiving the third beam so as to adjust the first steering angle, thereby outputting a fourth beam; and a driving unit for controlling a first light output angle, wherein a wave front of the second beams can be wider than that produced by diving a wave front of the first beam by k.
