Abstract (en)

[origin: WO2013056289A1] The invention relates to the real-time measurement of relative position data and/or of geometrical dimensions of a moving body (1) by lighting unit (2) and a detector unit (4), wherein the moving body (1) is movably guided relative to both of said units. Light beams (3) are transmitted from the lighting unit (2) towards the detector unit (4); the moving body (1) protrudes between the lighting unit (2) and the detector unit (4) into the volume flooded by the light beams (3), so that the shadow border of the shadow thrown by the moving body (4) extends over the detector unit (4). The detector unit (4) comprises a two-dimensional optical position detector (4.1), which is designed as a two-dimensional optical waveguide containing photo-luminescent particles. Signals from said two-dimensional optical waveguide are read out by a plurality of small-area photoelectric sensors (4.1.1) spaced apart from one another, the strength of the signals correlating with the intensity of the light (4.1.1) at the sensor location in waveguide mode.
