    "abstract": "Experiments were conducted to study light propagation in a light waveguide\nloop consisting of linearly and circularly moving segments. We found that any\nsegment of the loop contributes to the total phase difference between two\ncounterpropagating light beams in the loop. The contribution is proportional to\na product of the moving velocity v and the projection of the segment length\nDeltal on the moving direction, Deltaphi=4pivDeltal/clambda. It is independent\nof the type of motion and the refractive index of waveguides. The finding\nincludes the Sagnac effect of rotation as a special case and suggests a new\nfiber optic sensor for measuring linear motion with nanoscale sensitivity.",
