PURPOSE: A 3D laser range finder sensor is provided to enhance reliability by maximizing the linearity of rotation and lift operations and minimizing the error of 3D scanning. CONSTITUTION: A 3D laser range finder sensor comprises a reflective mirror(100), a rotating body(200), a lifting body(300), a connector(400) and an auxiliary lifting unit(500). The reflective mirror rotates, has a variable slope and reflects photon radiation and incident light. The rotating body supports the reflective mirror and rotates the mirror normally and reversely. The lifting body is coupled to the rotating body and lifts. The lifting body lifts separately from the rotating body and rotates integrally with the rotating body when the reflective mirror rotates. The connector extends according to the lift of the lifting body and changes the slope of the reflective mirror at a given rate. The auxiliary lifting unit lifts the lifting body at a given speed.
