Method for determining absolute coding of an optical coding track

The invention concerns a method for determining absolute coding represented by code elements of an optical code track, with illumination of the absolute coding with light, modulating of some of the illuminating light on code elements, determining of the absolute coding as modulated light and continu...

Beschreibung
Zusammenfassung:	The invention concerns a method for determining absolute coding represented by code elements of an optical code track, with illumination of the absolute coding with light, modulating of some of the illuminating light on code elements, determining of the absolute coding as modulated light and continuously varying modulation of the light on neighboring code elements.
