Abstract: An angle absolute encoder comprises a code rod encoded with code marks configured in segments, such that each successive segment has an increasing number of code marks, arranged at an angle to the rotation axis depending on the number of code marks in each segment. The angle of the code mark is determined by the number of code marks in the respective segment, the width of the segment parallel to the rotation axis of the code rod and the radius of the code rod. The angular resolution increases according to the number of code marks in each segment. Light is reflected from or transmitted through the code marks and detected by a light detector to determine absolute angle position.
