Firstly  the fine Moire signal of encoder which is collected with the high-speed data gathering card into the computer is treated to equiangular data with the method of linear interpolation. Then  the analysis of harmonic wave with the FFT is processed. Compared with the standard signal  the dynamic interpolation errors of the encoder are calculated. Experimental results show that the precision of the dynamic evaluation system of interpolation errors is 0.1 %( pitch). The evaluation system is simple  fast  high precision  and can be used in the working field of the encoder. 2009 SPIE.
