Abstract :
The noise due to the birefringence modulation of a nonideal phase modulator in a fibre-optic gyroscope is investigated. Theoretical analysis and experimental observation show that there is a definite ¿/2 phase difference between this noise and the Sagnac signal at the modulation frequency.
