A linear position measuring system (10) and a method for determining a position of a carriage in relation to a slide rail (12), with an incremental scale (14) placed along the slide rail (12) and a scanner secured to the slide scale. The scanner is designed to scan a plurality of incremental markings along the incremental scale (14), wherein the incremental markings can be scanned as an essentially analog signal progression. The scanner is designed to scan the incremental markings with a variable scanning frequency. The scanning frequency can be adaptively varied in relation to a currently acquired frequency of the analog signal progression, wherein the variable scanning frequency measures at least twice the currently acquired frequency of the analog signal progression. |
