Vorrichtung zur unterdrückung des relativen intensitätsrauschens in einem faseroptischen kreisel

System for suppression of relative intensity noise in a fiber optic gyroscope

A system is disclosed which suppresses relative intensity noise in a fiber optic gyroscope. A high-speed intensity modulator is placed in the gyroscope light path between the fiber light source and a tap coupler which provides a sample of the modulated signal for use in a feedback loop. A photodetector receives the sampled signal and provides current-to-voltage conversion of the signal. A high-bandwidth voltage amplifier then adjusts the gain and phase of the converted signal and drives the intensity modulator in such a manner as to stabilize the control loop and provide suppression of relative intensity noise. The present system modulates the intensity of the light at a frequency which is sufficiently high to allow suppression of high frequency components of the relative intensity noise.
