Abstract: Disclosed is a scanning unit for an optical position measuring device. The inventive device is suitable for scanning a periodic striped pattern within a detection plane and is highly insensitive with respect to short periodic disruptions of the scanned measurement partition. The scanning unit consists of at least one detector array provided with several radiation-sensitive detector elements which are disposed adjacent to each other in a first direction on a common carrier substrate with a period PDET. At least one second detector array consisting of several radiation-sensitive detector elements is arranged in an adjacent position to the first detector array in a direction which is perpendicular to the first direction on the plane of detection. The detector elements of the second detector array are also disposed adjacent to each other in the first direction.
