Abstract
In the photoelectric conversion method and apparatus applicable to displacement sensors irradiating light to objects and sensing the distances to the objects, distance-determining type photoelectric sensors etc., the method and apparatus arrange n (n>2) light-receiving elements in a predetermined direction, and divide each photoelectric current I1, I2, . . . , In of each light-receiving element in predetermined ratios k1 to 1-k1, k2 to 1-k2, . . . , kn to 1-kn; and lead the divided photoelectric currents to the first and the second photoelectric current output terminal, and control the predetermined ratios k1, k2, . . . , kn in keeping such relationships as k1>0.5>kn and km.ltoreq.kp (p=m-1; m=2 to n), therefore the arbitrary positions on the light-receiving surface can be set in high sensibility, and high speed responsibility can be attained.
