Abstract: Disclosed is a lidar deviceincluding a transmission unit configured to emit a first signal, which is an optical signal; a first lens unit configured to convert the first signal into parallel light; a reflection unit configured to adjust a direction of the converted first signal; a second lens unit configured to enable the first signal to have the same focal plane even when a reflection angle of the reflection unit changes; a third lens unit configured to convert the first signal passing through the second lens unit into parallel light; a fourth lens unit configured to increase an angle of the first signal passing through the third lens unit; and a reception unit configured to receive a second signal, which is light reflected by an object after passing through the fourth lens unit.
