摘要

我们演示了一种紧凑的光纤信号传输延迟测量系统。微波信号的频率被锁定在可以在频域获得的信号传输延迟上。利用频率扫描模糊度解析系统，可以精确地确定信号的传输延迟。实时监测系统的延迟波动，并从测量结果中减去。该方法实现了亚皮秒级的不确定度。

Accurate Signal Transmission Delay Measurement in Optical Fibers with Self-Calibration Configuration

We demonstrate a compact signal transmission delay measurement system in optical fibers. The frequency of a microwave signal is locked to the signal transmission delay which can be obtained in frequency domain. With a frequency-scanning ambiguity resolving system, the signal transmission delay can be precisely determined. The system delay fluctuation is monitored in real-time and subtracted from the measurement result. This method achieves sub-picosecond uncertainty.
