Fibre-optical measuring system, gyrometer, navigation and stabilization system

摘要

The invention relates to a fibre-optical measuring system of the type in which the variation of a parameter generates a difference of rate. Such a device enables the measurement of speed of rotation or of current and of magnetic field. This device comprises electronic means performing a digital processing of the signal and optimising its performance levels. It comprises: - an analogue-digital converter (11), - a digital processing system (12), - a digital servocontrol-loop filter (13), - a register (14) furnishing a signal dependent on the measured parameter, - an accumulator (15), - a digital-analogue converter (16).
