QUASIOPTICAL VIBRATORY GYROSCOPE Russian patent published in 1995 - IPC

FIELD: electronic engineering. SUBSTANCE: quasioptical vibratory gyroscope has electron-beam gun with annular cathode. Electron beam goes along axis of other electron beam and in the process it converges by aid of static magnetic field which causes its gyration. This beam excites in quasioptical cavity standing electromagnetic alternating field of definite wavelength. Cavity has two mirrors facing each other on axis perpendicular to electron beam axis. Annular cathode is built up of alternating high and low emissive capacity segments so that electron beam current density is varying in azimuth; sections with low emissive capacity are arranged opposite to nodal surfaces of standing electromagnetic field of cavity. EFFECT: improved efficiency of vibratory gyroscope. 9 cl, 3 dwg
