Abstract
A method for calibrating an encoder scale having an array of marks in a first direction, includes moving the encoder scale in the first direction relative to a first encoder-type sensor, a second encoder-type sensor and a third encoder-type sensor, wherein the first encoder-type sensor and the second encoder-type sensor are fixedly spaced in the first direction at a first distance relative to each other, wherein the second encoder-type sensor and the third encoder-type sensor are fixedly spaced in the first direction at a second distance relative to each other.
