The invention relates to a method and a device for opto-electronically determining the position of an object (50) using a measurement 
assembly, which is separated from the object (50) by a medium (31, 52) that is permeable to at least one type of specific 
radiation. The measurement 
assembly consists of at least one active sensor zone (S) in the medium comprising at least two measuring paths (x, y), which are maintained by at least two 
radiation sources (1, 3) that emit the specified 
radiation and by at least one radiation 
receiver (2) that is allocated to the radiation sources. Said 
receiver determines the reflection (53) returned by the object (50) to generate a detection 
signal which corresponds to the received radiation. A specified radiation is emitted using the radiation sources (1, 3) and the reflection (53) returned by the object (50) is detected, in order to allocate initial values (U(t), UR(d)) to the individual measuring paths. The invention is characterised in that an evaluation unit (55) determines the position and / or displacement of the object (50) by determining a specified angular curve of the object in relation to the radiation sources (1, 3, 57) from the initial value (UR(T), UR(d)), for a known 
spatial relationship between the radiation sources. This allows the position and / or displacement of an object to be opto-electronically detected in a simple and practical manner.
