  • Patent number: 11874399
    Abstract: Disclosed is a Light Detection and Ranging (LIDAR) sensor which is capable of minimizing the size of a LIDAR sensor which is capable of performing 3D scanning and setting a region of interest for obtaining point cloud data with the removal of light scattering, by separating a transmitter module and a receiver module; disposing a transmitter, a mirror, and a receiver in a specific space so that light emitted from a light source or light reflected from a transmission mirror is reflected from a first reflection region of a moving mirror and is then moved to a target object, after which light reflected from the target object is reflected from a second reflection region of the moving mirror and is moved to the transmission mirror or a photodiode; installing a blocking wall separating movement paths of light; and adjusting the range of movement of the moving mirror.

  • Publication number: 20230097670
    Abstract: The present exemplary embodiments propose a LIDAR sensor including: a transmission/reception module which transmits transmission light and receives reflection light reflected from an object; a reflector assembly which has an empty space to assemble the transmission/reception module at one side, receives the transmission light from the transmission/reception module to reflect the transmission light toward the object and transmits the reception light reflected from the object to the transmission/reception module, a rotary module assembly which rotates the transmission/reception module and generates an RPM and a rotation angle based on a light reception amount of the reflection light which is received by a sensor unit by reflecting the transmitted light; and a fixing module which supports the transmission/reception module and the rotary module.
