| Abstract: | The reasons of the high-frequency signals and noise signals generated from the Moire fringe optolectric signal and the relative method of self-adaptive filtering were discussed,in order to improve the quality of Moire fringe optoelectric signals of the incremental optoelectric encoder,decrease the impact of high-order harmonic frequency in the main count signal and increase the SNR for the stable output of sinusoidal waveform.The window function of the grating pair from both macro and micro perspectives,and... |
