The optical position measuring device has a material measure (10) which is connected with one of the two objects and has an incremental line (12) extended in measuring direction (x) and a reference marking (11) at a reference position (x-REF). A scanning unit is connected with the other of the both objects and has a divergent radiated light source, one or multiple grids and a reference signal-detector arrangement. The reference signal-detector arrangement has four detector arrays with multiple detector elements. |
