摘要： The distance measuring apparatus according to the present invention may comprise: a light emitting unit for emitting light; a light receiving unit comprising one or more cells configured to receive incoming light and output a signal corresponding to an amount of the received light; a motor; a first rotary unit for changing a path of outgoing light which is emitted from the light emitting unit while being rotated by the motor; and a second rotary unit for changing a path of the incoming light so that the incoming light enters the light receiving unit while being rotated by the motor synchronously with the first rotary unit. Therefore, it is possible to simplify the structure of the apparatus which measures distances in a wide angular range.

摘要： The distance measuring apparatus according to the present invention may comprise: a distance measuring unit; a motor; and a rotary wireless transceiver, comprising a rotor core rotated by the motor, a stator core, and power coils and signal coils respectively wound around the rotor core and the stator core, configured to wirelessly supply power to the power coil wound around the rotor core via the power coil wound around the stator core and wirelessly transmit the signal output from the distance measuring unit to the signal coil wound around the stator core via the signal coil wound around the rotor coil. The rotor core and the stator core may be in a shape of a circular plain such that the rotor core and the stator core face each other with a plane, perpendicular to a rotation axis of the motor, interposed between them.
