摘要： An optical divider is disposed, in front of at least one of the transmitter and receiver elements, therebetween, and at least one of a transmission and reception side, and has a plurality of optical dividing pieces each having an optical deflection surface on which an angle of a detection ray is varied to a plurality of angles for dividing the detection ray toward a plurality of division areas. The optical deflection surface on at least one of the transmission and reception side is set to have a given angle, to assign at least one of the detection ray from the transmitter elements and toward the receiver elements, to a given division area, such that a combination of the transmitter and receiver elements forming one of the division areas is different from a combination of the transmitter and receiver elements forming another one of the division areas.
