OPTOELECTRONIC POSITION MEASUREMENT DEVICE AND POSITION MEASUREMENT METHOD

The invention relates to an optoelectronic position measurement device (1) and an optoelectronic position measurement method. The optoelectronic position measurement device (1) comprises a code carrier (6), having an optically ascertainable position code (PC), a radiation source (2) and a detection unit (14) having a first sensor unit (13) that has a light-sensitive receiving region (12). A scanning signal dependent on the position code can be generated in this way, and a position of the code carrier (6) relative to the first sensor unit (13) can thus be captured. The code carrier (6) can be moved relative to said sensor unit (13) by one degree of freedom. A refractive optical element (8) having a focusing segment (10) and at least one neighboring segment (9, 11) are arranged between the code carrier (6) and the first sensor unit (13). Optical radiation (3) shining in on the focusing segment parallel or at an angle of incidence below a threshold angle a to the optical axis (OA) of the focusing segment (10) can be guided by the focusing segment (10) on the receiving region (12) of the first sensor unit (13) within the optical axis (OA), and radiation that is shining into a deflection angle region above the threshold angle a to the optical axis of the focusing segment can be deflected by the focusing segment and the neighboring segment to a point outside of the optical axis of the focusing segment.
