Abstract
An optically scanning displacement sensor is arranged to compute by means of a triangulation an inverse function from a first measured distance signal proportional to output position signals from a position detecting means which receiving reflected light from an object to be detected, and the first measured distance signal is multiplied at a linearity correcting means by a signal of a sum of the inverse function and a constant so as to compute a second measured distance signal, whereby a two-dimensional position detection can be realized with the least required memory capacity and the minimum adjusting process.
