Technical Examples
  1. An optical displacement sensor comprises: a light source; a light receiving means adapted to receive light emitted from the light source; and a light diffracting element disposed between the light source and the light receiving means. The light receiving means include a first light receiving element group centrally located, and a second light receiving element group constituted by two separate clusters disposed so as to sandwich the first light receiving element group, and the light diffracting element functions to diffract the light emitted from the light source along one direction of the two-axis directions into a zero-order beam to be received at the first light receiving element group, and higher-order beams received at the second light receiving element group.
