FIELD: measurement technique. ^ SUBSTANCE: invention refers to praetersonic instruments intended for converting rotational speed of objects into electric signal and may be used in systems for navigation, orientation and control of moving objects. Gyroscope contains plate 1 of piezoelectric material on one side of which following structures are applied: regular structure 2 of inertial masses, active interdigitated transducer (IDT) 3 with reflecting structure 4, initiating surface-active waves (SAW) in one direction and located in transversal direction measuring IDTs 5 and 6 of summary SAW field from regular structure of inertial masses consisting of diffraction and signal from Coriolis forces SAW fields. Opposite to active IDT after regular structure of inertial masses, absorbing IDT 7 is applied on piezoelectric plate. Outputs of this IDT 7 are connected by conductors 8 to electric resistance of load 9 which can be made composite and variable. ^ EFFECT: invention makes possible to improve sensibility and fabricability. ^ 3 cl, 1 dwg |
