    摘要: The invention relates to a measuring head system (1) for a coordinate measuring machine, having a scanning element (6), which has a part provided for contacting a measured object as a contacting part (5), which can be moved in relation to a fixed measuring head base (2) in a lateral x direction (20) and a lateral y direction (21), such that an object to be measured can be mechanically scanned using the scanning element (6). An optical sensor (10), having a sensor line (11) which can be read out and comprises a plurality of array sensor elements, is fixed on the measuring head base (2). Furthermore, means are provided, which are particularly disposed spatially fixed to the contacting part (5), generate a projection—as a function of displacements of the contacting part (5) in relation to the measuring head base (2)—on the sensor line (11) using at least one radiation source (15). In addition, an analysis unit is provided. The means have at least one first mask element (17), which is implemented to generate a first partial projection on the sensor line (11) such that said partial projection is optimized to determine an x displacement and a y displacement of the contacting part (5) in relation to the measuring head base (2) in the x direction or y direction. The analysis unit is configured to determine the x displacement and the y displacement from signals only generated by the one sensor line (11).
