<p>The method involves dynamically calculating angular interpolation according to initial values of signals from photo detectors (4-7) of an optic encoder. The calculation is done iteratively by finding a sign of the values of previous iteration and calculating new values to find the sign to be used in a next iteration, and a value approaching an angle value to be known. The angular value is obtained in a period of 180 degrees. An independent claim is also included for a high resolution optic encoder.</p> |
