| Abstract: | Using a Hilbert transform Modulator, the intensity distribution of first-order spectrum of crossed-slit is used for accuracy positioning in practice. Simulating experimental results show with care this method will give an accuracy of better than 10~(-6) and can be applied to test the flatness of guideway or platform, |
