<p>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 </= 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. <IMAGE></p> |
