Abstract: A dynamic micro-displacement measurement system based on Doppler effect is introduced. The system includes He-Ne laser source,frequency conversion and direction discrimination,the high-speed CCD video signal gather system,the processing system of computer and interference fringes handling software wraps. The precision,sensitivity and stability in this system have been improved compared with traditional measurement technique,the full automatic measurement of micro-displacement is realized.
