LASER FIBRE-OPTICAL TRANSDUCER OF ANGULAR VELOCITY |
摘要 |
FIELD: navigational systems. SUBSTANCE: suspension carries source of laser radiation, modulator, beam splitter and sensitive element. Sensitive element is multiturn coil of fibrous light guide. Sensitivity axis of coil is perpendicular to axis of suspension. Photodetector is optically coupled through sensitive element and beam splitter to source of laser radiation. Polarizer is positioned between source and modulator. Reference voltage generator is manufactured in the form of transducer of angular position of axis of suspension. Register and transducer of angular position are connected to circuit for integration, determination of phase angle of turn of suspension and subtraction which ensures increased accuracy of determination of two components of angular velocity of object. EFFECT: increased accuracy of determination of two components of angular velocity of object. 1 cl, 3 dwg
