| Abstract: | The paper presents the principle with which the system can transmit the measured and the reference signal through dual -path optical fiber. At first, we discuss the method of restraining temperature drift for improving the measuring accuracy and the characteristic of anti-electric magnetic interference. At last,the paper gives the experimental results of temperature drift restrained and displacement measured. |

| Keywords: | Optical fiber Split time Dual-path Temperature drift restrained |
