Abstract :
Based on high-stability and high-speed of signal transmission and the relationship between time and space, a new measurement approach of a short time interval is proposed. Because the transmission length of the time signal is easier to be measured and processed with high-precision, combining with the phase coincidence detection, the measurement precision of the approach is much higher than that of the unit subsection of transmission lines for start and stop signals. This technique can show much finer than several tens of ps resolution and even better in the future.
