光の片道速度
This experiment proves with greater accuracy that the signal return path to the measuring device has a constant delay, independent of the end point of the light flight path, allowing measurement of the time of flight in a single direction.
J. Finkelstein claimed that the Greaves et al. experiment actually measures the round trip (two-way) speed of light.
In the November issue of the Indian Journal of Physics, Ahmed et al. published a comprehensive review of One-Way and Two-Way Experiments to test the isotropy of the speed of light.
Regardless of those different interpretations, the observed agreement between those synchronization schemes is an important prediction of special relativity, because this requires that transported clocks undergo time dilation (which itself is synchronization dependent) when viewed from another frame (see sections Slow clock-transport and Non-standard synchronizations).
