Method and incremental encoder for determining the actual position of a body along a measuring path with a material measure that has at least one gap

摘要

The method involves forming a gap (10) of position encoding element (7) of incremental encoder (1) along the measurement path (W). Several position markers (8) are provided in the position encoding element having predetermined frequency (Fi), and are scanned to generate a signal (S) representing the actual position. The predetermined frequency is converted into set spatial frequency (Fs) irrespective of the length (L) of the gap, for generating the signal. An independent claim is included for incremental encoder.
