Abstract: The invention relates to an optical transducer for measuring position, angle, and the time dependence of these quantities in one, two or three dimensions, with at least one fiber optical transducer having light-emitting means which feeds incident light to an object on which the measurement is to be effected, a photo-detector which senses light emanating from the object after said incident light has been influenced by the object and an electronic unit partly for controlling the light-emitting means, and partly for evaluating the output of the photo-detector, the output signal being dependent on the variations in light transmission, light absorption, light reflection and/or photo-luminescence of a pattern on the object. The variations of one or more of the optical properties of the pattern in at least one direction have at least three different amplitude values which occur in a specific order, and that the relative amplitude values between variations of the optical properties, which variations are consecutive in space, are detected and evaluated by the electronic unit for determining the direction of movement and the position of the transducer relative to the object.
