Optical gyros, such as ring laser gyros and fiber optical gyros, have become a basis for strapdown inertial navigation systems due to a number of advantages (larger dynamic range of the measured velocities; high stability of scale factor, insensitivity to linear acceleration and G-stress; smaller readiness time, etc.). Despite success in its development, ring laser and fiber optic gyros are unsuitable for using in control systems of small portable devices because of its large size and weight. Now the actual task is miniaturization of optical gyros, or development and research of microoptical gyros.
