Abstract: Provided is a 3-dimensional (3D) scanning technique using a laser. The technique includes a laser outputting device configured to emit omni-directionally a laser beam output from a laser beam source in 360 degrees and a laser receiving device formed above or below the laser outputting device and configured to receive a laser beam reflected by an object which is located on a propagation path of a laser beam output from the laser outputting device.

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.

Abstract: A light detection and ranging (LIDAR) time of flight (TOF) sensor for inputting and outputting simultaneously and 3-dimensional laser scanning system including the same are disclosed. In one aspect, the sensor includes a substrate and a light receiving element array provided on the substrate and including a plurality of light receiving elements. The sensor also includes readout circuits configured to receive electrical signals from the light receiving elements and perform signal processing on the electrical signals. The sensor further includes metal lines disposed on the light receiving element array in parallel, provided to correspond to the number of the light receiving elements, and configured to connect the light receiving elements to the readout circuits in one-to-one correspondence.

Abstract: The described technology relates to a light detection and ranging (LIDAR) device. The LIDAR device can include a transmitter configured to emit an optical signal, a first lens section configured to convert the optical signal into collimated light, a reflector configured to adjust a direction of the converted optical signal, a second lens section configured to allow the adjusted optical signal to have the same focal plane even though a reflection angle of the reflector is varied and a third lens section configured to convert the optical signal passed through the second lens section into collimated light. The LIDAR device can also include a fourth lens section configured to allow the optical signal, and a receiver configured to receive the optical signal passed through the fourth lens section. The third lens section and the fourth lens section are positioned on the same line in a first direction.
