Abstract: The invention relates to an optoelectronic displacement or angle measuring device, comprising a coded disc (1) and a photosensitive sensor device (2), fixed to the above, with a number of adjacent photoelectric converter elements (W), arranged transverse to the longitudinal direction of the coding (3) and an illumination device for optical imaging of the coding (3) on the coded disc (1) onto the photosensitive surface of the sensor device (2). The coded disc (1) comprises a digital code (3) and an analog encoded track consisting of a number of individual, coded segments (7, 7′), arranged sequentially in a row, in the direction of the measured path and which is defined in that the analog encoded track forms part of a continuous reference code track (4), symmetrical about the mid-point, the code segments (7, 7′) of which are placed sequentially in a row and which define an uninterrupted analog code track.
