A rotational rate gyroscope for detecting rotation thereof comprises a base member, a primary oscillator supported by its primary oscillator suspension so as to be movable with respect to the base member, and a secondary oscillator supported by a secondary oscillator suspension, separate from primary oscillator suspension, so as to be movable with respect to the primary oscillator. The secondary oscillator suspension is designed such that movement that can be applied to the primary oscillator can be transferred to the secondary oscillator, whereas the movement of the secondary oscillator effected by the Coriolis force substantially is not transferred back to the primary oscillator. In addition thereto, the major surfaces of the primary oscillator and of the secondary oscillator extend substantially in the same plane, with the movement of the primary oscillator and/or of the secondary oscillator also taking place in this plane.

Rotational rate gyroscope with decoupled orthogonal primary and secondary oscillations

An interference filter having a layer with an area consisting of a porous material extending from the surface of the layer to the interior, the dimensions of the porous layer area in a direction normal to the layer surface have different values to provide for varying reflection or, respectively, transmission characteristics.

A rotational rate gyroscope ( ) for detecting rotation thereof comprises a base member ( ), a primary oscillator ( ) supported by its primary oscillator suspension ( ) so as to be movable with respect to the base member ( ), and a secondary oscillator ( ) supported by a secondary oscillator suspension ( ), separate from primary oscillator suspension ( ), so as to be movable with respect to the primary oscillator ( ). The secondary oscillator suspension ( ) is designed such that movement that can be applied to the primary oscillator ( ) can be transferred to the secondary oscillator ( ), whereas the movement of the secondary oscillator ( ) effected by the Coriolis force substantially is not transferred back to the primary oscillator ( ). In addition thereto, the major surfaces of the primary oscillator ( ) and of the secondary oscillator ( ) extend substantially in the same plane, with the movement of the primary oscillator ( ) and/or of the secondary oscillator ( ) also taking place in this plane.
