Abstract: A distance measurement sensor that detects a distance to an object based on heterodyne detection using light generated from a light source and another light received by a light receiver, includes: a scanning unit which scans the light in a first direction; a diffusing lens which diffuses the light in a second direction; multiplexers which multiplex the light and the another light to provide optical signals, respectively; and a processor which detects the distance to the object based on the optical signals. The light receiver has light receiving antennas in the second direction. The multiplexers are connected to the light receiving antennas, respectively. The processor performs a parallel processing for detecting the distance to the object based on the optical signals with respect to the light receiving antennas individually.
