摘要
为了满足长距离光纤时间传递的工程要求,提出了一种基于时间数字转换(TDC)和现场可编程门阵列(FPGA)的时延测量方法。该方法将FPGA测量范围大和TDC分辨率高的特点相结合,实现了大范围高分辨率的光纤时延测量。研究结果表明,该系统的测量范围为0~1 s,分辨率为22 ps,不确定度优于100 ps。
Abstract
In order to meet the engineering requirements of long haul time transfer over optical fibers, a time-delay measurement method based on the time digital conversion (TDC) and the field programmable gate array (FPGA) is proposed. This method combines the characteristics of a large measurement range for FPGA and a high resolution for TDC, and thus an optical fiber time-delay measurement with a high resolution in a wide range is realized. The research results show that the measurement range of this system is 0-1 s, the resolution is 22 ps, and the uncertainty degree is superior to 100 ps.
