    "abstract": "A fiber optic conveyor has been developed for investigating the travel-time\ndifference between two counter-propagating light beams in uniformly moving\nfiber. Our finding is that there is a travel-time difference\nDeltat=2vDeltal/c^2 in a fiber segment of length Deltal moving with the source\nand detector at a speed v, whether the segment is moving uniformly or\ncircularly.",
