Position measuring device
A position measuring device including a code having a sequence of code elements of equal width B that is disposed in a measurement direction and includes a first property and a second property. The sequence of codes elements includes a first set of code elements having the first property and a second set of code elements having the second property, wherein the first and second sets of code elements are each being disposed aperiodically. The position measuring device further including a scanning unit having a plurality of detectors for scanning the code and obtaining scanning signals, wherein a code word defining an absolute position is defined from the scanning signals. The position measuring device including an arrangement for forming an incremental signal from the scanning signals, wherein the arrangement includes a converter device and a collection device arranged downstream of the converter device and wherein the collection device forms respective intermittently periodic partial signals from the scanning signals derived from scanning positions in a spacing matrix.
