LIDAR sensor that cancels noise by shielding EMI and light leakage

A moving object, comprising:

• a LIDAR sensor configured to transmit transmission light and configured to receive reception light and configured to remove transmission light or reception light moving in a predetermined direction;
• and
• a moving device which is configured to move the moving object,
• wherein the LIDAR sensor includes:
• a transmission and reception module which is configured to transmit transmission light and configured to receive reception light reflected from an object and includes a shielding assembly unit located between a path through which the transmission light moves and a path through which the reception light moves;
• a reflector assembly which has an empty space to assemble the transmission and reception module at one side, and is configured to receive the transmission light from the transmission and reception module and is configured to reflect the transmission light toward the object and is configured to transmit the reception light reflected from the object to the transmission and reception module;
• a rotary module configured to rotate the transmission and reception module;
• and
• a fixing module which supports the transmission and reception module and the rotary module,
• wherein the transmission and reception module includes:
• a first body tube which provides a path through which the transmission light moves and is assembled with a transmission lens on a front surface,
• a second body tube which is spaced apart from one side surface of the first body tube, providing a path through which the reception light moves, and is assembled with a reception lens on a front surface,
• a circuit board which is assembled on rear surfaces of the first body tube and the second body tube, configured to transmit the transmission light and receive the reception light to acquire distance information to the object, and
• a baffle which is slidably assembled in assembly grooves formed on one side surfaces of the first body tube and the second body tube configured to cancel a noise due to the transmission light and the reception light,
• wherein the shielding assembly unit which is assembled between the first body tube and the second body tube is configured to restrict the movement of the transmission light which passes through the first body tube to the second body tube and the movement of the reception light which passes through the second body tube to the first body tube,
• wherein the baffle includes a light transmission baffle which is assembled on the first body tube and has at least one groove through which the transmission light passes and a light reception baffle which is assembled on the second body tube and has at least one groove through which the reception light passes.
