| Abstract: | The grating moire fringe signal is the core of the grating measuring sensor, and its signal quality will directly affect the measuring accuracy. This paper applies the tracking differential method to the filtering of grating moire fringe signal. The simulation experiment shows that the method can track and reproduce the original signal well, and can solve the noise problem of Moire fringe signal well. It has good real-time performance and improves the quality of Moire fringe signal. |
