Optical counterpart of the Foucault pendulum
Abstract
The twin beam vortex interferometer with phase-conjugating mirror is analyzed in rotating reference frame.Circular motion of the interference pattern occurs due to exchange of the angular momenta between photons and interferometer. Using the concept of the ideal phase-conjugating mirror it is shown that motion of the helical interference pattern of the interacting vortex photons with topological charge may be used for the detection of the slow rotations. The higher density of interference fringes may improve the sensitivity by factor containing 2 compared to the conventional Michelson interferometry.
