ABSTRACT:
A displacement sensor includes a light emitter for emitting light towards a target object, a detector for receiving reflected light from the target object and generating a detection signal which depends on the distance to the target object, a signal processor for calculating the distance to the target object from the detection signal. The signal processor receives from another sensor a data item representing a distance value calculated by the latter and carries out a specified calculation using also the result of calculation with the calculated distance obtained by itself and said calculated distance data item and to output the result of said calculation.
