Abstract

Optical location sensor with a sensor part consisting of an optical light wave tube and integrated optical light wave tubes arranged in parallel by which the displacement or location is measured by the ratio between the lighting effects which are connected to the light wave tubes from the light wave tube, for example from an optical fibre, which ratio is not affected by the lighting effect which progresses inside the fibres. <IMAGE>
