SYSTEM FOR MEASURING THREE-DIMENSIONAL LINEAR AND ANGULAR ACCELERATION AND MOVEMENT OF AN OBJECT IN SPACE USING FIBER BRAGG GRATINGS Russian patent published in 2020 - IPC G01C19/72 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment. Essence of the invention is that the system for measuring three-dimensional linear and angular acceleration and movement of an object in space using fiber Bragg gratings comprises a unit for generating a broadband light flux signal, a fiber-optic light guide, an optical circulator, a digital computing device, wherein the measurement sensor comprises a sealed housing, a measuring weight is fixed inside the housing by means of a fiber-optic light guide, on each measurement section between the housing and the measuring weight, the fiber-optical light guide comprises a fiber Bragg grating, on the last measurement section the fiber-optic light guide is fixed on the vibration-insulating platform, which in its turn is fixed on housing at distance from gauge weight.

EFFECT: high accuracy and reliability of measuring acceleration, vibration and movement of an object.
