Abstract
The described technology relates to a light detection and ranging (LIDAR) device. The LIDAR device can include a transmission unit configured to emit a first 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 and 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. The LIDAR device can also include 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 reflected by an object after passing through the fourth lens unit.
