A system including a beam steering device, includes a substrate, at least one light source disposed on the substrate and configured to irradiate at least one light beam, and optical phased arrays disposed on a same plane of the substrate and configured to adjust a direction of the at least one light beam that is irradiated, to output a first plurality of light beams to an object. Each of the optical phased arrays has a different view angle range. The system further includes light detecting elements configured to detect a second plurality of light beams that are reflected by the object to which the first plurality of light beams is output. The light detecting elements respectively correspond to the optical phased arrays.
