Abstract
A scattered light Moire-Brillouin guided wave gyroscope includes a coherent light source for providing two counter-rotating primary waves; an optical waveguide, responsive to the two primary waves, for generating a Moire fringe from a primary fringe and a Brillouin fringe derived respectively from the counter-rotating primary waves and from the counter-rotating Brillouin waves produced from the primary waves; and means for detecting the rotation of the Moire fringe relative to the waveguide.
