摘要
本文提出利用时分双信道传输测量与参考信号的原理,阐述抑制电涡流传感器探头温漂,提高测量精度的技术措施,讨论光纤远距离传输的防电磁干扰等特性,给出了温漂抑制、位移等性能指标的试验结果。
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.
