Optical incremental encoders are used to gauge the displacement or the angle of tool machines etc. This thesis investigated the design and hardware implementation of higher interpolation circuits. By subdividing of encoder output signals the measured resolution can be upgraded twenty times and achieves to the range of 1 micrometer. Error analysis of possible methods is discussed in this thesis, and the experiment results will offer us an information for the implement of subdivided circuits.
