Abstract
An absolute angle coding that includes a first code sequence disposed within 360°, wherein the first code sequence has a first length and is disposed NA times in succession. The absolute angle coding includes a second code sequence disposed within 360°, wherein the second code sequence has a second length and is disposed NB times in succession, wherein the first code sequence and the second code sequence in combination absolutely unambiguously encode said 360°. In addition, NA is greater than or equal to 2 and NB is greater than or equal to 2 and NA is not equal to NB. The first length is not equal to the second length and the first code sequence and the second code sequence are disposed in one common track, in that a part of the first code sequence and a part of the second code sequence are disposed in alternation.
