Modified Sagnac experiment for measuring travel-time difference between counter-propagating light beams in a uniformly moving fiber

Physics Letters A. A fiber optic conveyor has been developed for investigating the travel-time difference between two counter-propagating light beams in uniformly moving fiber. Our finding is that there is a travel-time difference ??t=2v??l/c2 in a fiber segment of length ??l moving with the source and detector at a speed v, whether the segment is moving uniformly or circularly.
