| Abstract: | In this paper, the author introduces a new technique to measure the lengthwaysdisplacement by laser Doppler technology, poses a optical way and use phasic raster to separateDoppler signal. This method has the advantages of high SNR and strong signal intensity. Experiments prove that this method is correct in principle and can be used practically. |
