We have applied the interference fringe scanning algorithms that are used in interference fringe analysis to an optical encoder as angle detection algorithms, in order to disperse the influence of sinusoid wave distortion from the encoder's photo detector. We also evaluated these algorithms with the analytical system and techniques for obtaining the same output signal as that of the actual encoder, by using image data on light intensity as the light permeates the slit disk of the encoder. As a result, we obtained about twice the angle precision by applying the algorithms to the optical encoder.
