  2. Gyroscope - Wikipedia

    en.wikipedia.org/wiki/Gyroscope

    The hemispherical resonator gyroscope (HRG), also called a wine-glass gyroscope [52] or mushroom gyro, makes use of a thin solid-state hemispherical shell, anchored by a thick stem. This shell is driven to a flexural resonance by electrostatic forces generated by electrodes which are deposited directly onto separate fused-quartz structures that ...

  3. Vibrating structure gyroscope - Wikipedia

    en.wikipedia.org/wiki/Vibrating_structure_gyroscope

    A vibrating structure gyroscope (VSG), defined by the IEEE as a Coriolis vibratory gyroscope (CVG), [1] is a gyroscope that uses a vibrating (as opposed to rotating) structure as its orientation reference. A vibrating structure gyroscope functions much like the halteres of flies (insects in the order Diptera).

    The HRG, unlike optical gyros (fibre-optic gyroscope and ring laser gyroscope), has inertial memory: if the power is lost for a short period of time (typically a few seconds), the sensitive element continues to integrate the input motion (angular rate) so that when the power returns, the HRG signals the angle turned while power was off.

  5. Nutation - Wikipedia

    en.wikipedia.org/wiki/Nutation

    The physics of nutation in tops and gyroscopes can be explored using the model of a heavy symmetrical top with its tip fixed. (A symmetrical top is one with rotational symmetry, or more generally one in which two of the three principal moments of inertia are equal.) Initially, the effect of friction is ignored.

  6. Quantum gyroscope - Wikipedia

    en.wikipedia.org/wiki/Quantum_gyroscope

    A quantum gyroscope is a very sensitive device to measure angular rotation based on quantum mechanical principles. The first of these was built by Richard Packard and his colleagues at the University of California, Berkeley. The extreme sensitivity means that theoretically, a larger version could detect effects like minute changes in the ...

  7. Ring laser gyroscope - Wikipedia

    en.wikipedia.org/wiki/Ring_laser_gyroscope

    A ring laser gyroscope (RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation.

  8. Fibre-optic gyroscope - Wikipedia

    en.wikipedia.org/wiki/Fibre-optic_gyroscope

    A fibre-optic gyroscope (FOG) senses changes in orientation using the Sagnac effect, thus performing the function of a mechanical gyroscope. However its principle of operation is instead based on the interference of light which has passed through a coil of optical fibre , which can be as long as 5 kilometres (3 mi).

  9. Foucault's gyroscope - Wikipedia

    en.wikipedia.org/wiki/Foucault's_gyroscope

    Foucault published two papers in 1852, one focused on astronomy with the weight free to move on all three axes (On a new experimental demonstration of the motion of the Earth, based on the fixity of the plane of rotation) [8] and the other on mechanics with the weight free to move on only two axes (On the orientation phenomena of rotating bodies driven by a fixed axis on the Earth's surface.
