Abstract

In order to improve the resolution of an optical grating encoder it is very effective to divide the encoder signal. In this paper a new method for dividing encoder signals is developed. Its basic principle is based on a new kind of advanced tech''iique to obtain the fraction period section of an encoder signal by means of velocity measuement and consequently the signal can be divided finely. By means of this method not only does the dividing precision suffer no effects from possible errors owing to sinusolidality orthogonality and direct electric potential of signals but also the method is suitable for dynamic measurement of small computational load.
