ABSTRACT:
Light projected by a light projecting portion and reflected by an object is received by two sensor arrays (105, 106). Difference signals between signals respectively added by ring CCDs (113b, 114b) in correspondence with the ON and OFF states of the light projecting portion are calculated, and the distance to the object to be measured is calculated on the basis of the relative values of the positions of the difference signals on the sensor arrays (105, 106). The two sensor arrays (105, 106) form the base length, and the light projecting portion (104) is disposed at a position offset from the base length.
