摘要
System for determining positions along a direction of advance, having a first sensor, particularly a line sensor, having a scanning length (L) for scanning a first 2D pattern and producing a scan signal. The first 2D pattern has pattern elements that each form a first code word on at least one portion of the scanning length (L), which first code word codes a position along the direction of advance absolutely. In addition, the first code word can be taken as a basis for determining a deviation from an ideal position for the first sensor in relation to the first 2D pattern.
