摘要：A method for position measurement that includes scanning a plurality ofgraduation periods of one incremental graduation by a detector arrangement extendingover a length of one measurement range, a reference marking being integrated with oneof the graduation periods, and generating a plurality of periodic scanning signals, of
which at least one is locally modified by the reference marking. Detecting the at leastone scanning signal, modified by the reference marking, from among the plurality ofperiodic scanning signals. Determining an absolute position of the reference markingwithin the length of said measurement range as a function of the scanning signaldetected.
