ABSTRACT:
A phase difference sensor is arranged toward a target object such that the sensor can rotate at least 180° on its sensor optical axis. As the phase difference sensor rotates, the angle of a sensor viewing field is changed, and the distance to the target object is correctly computed using results measured before and after the change in the angle.
