Title: DISTANCE MEASUREMENT SENSOR
Abstract:
This distance measurement sensor is provided with: a scan unit (5) for scanning light, which is generated by a light source (1), in a direction corresponding to one direction; a diffusion lens (18) for diffusing the light, which is generated by the light source (1), in a direction corresponding to the other direction; a plurality of multiplexers (7) which multiplex the light generated by the light source (1) and light radiated to a light receiver (6), and thereby generate a light signal; and processing units (8, 9, 10) which calculate the distance to an object on the basis of the light signal generated by the multiplexers (7). The light receiver (6) has a plurality of light receiving antennas (21) arranged in the direction corresponding to the other direction, the multiplexers (7) are connected, respectively, to the plurality of light receiving antennas (21), and on the basis of the light signal generated by the multiplexers (7), the processing units (8, 9, 10) respectively perform calculations of the distance to the object for the plurality of light receiving antennas (21), said calculations being performed in parallel.
