OPTICAL SIGNAL NOISE REDUCTION FOR FIBER OPTIC GYROSCOPES
The RIN (random intensity noise) component of the random walk error of a fiber optic gyroscope can be reduced by utilizing an unpolarized light signal during processing. By depolarizing the light wave modulated by the fiber optic sensing coil or combining it with the unmodulated light wave of orthog...

| description | The RIN (random intensity noise) component of the random walk error of a fiber optic gyroscope can be reduced by utilizing an unpolarized light signal during processing. By depolarizing the light wave modulated by the fiber optic sensing coil or combining it with the unmodulated light wave of orthogonal polarization, a 3 db reduction in RIN can be achieved.
L'élément bruit d'intensité aléatoire (RIN) de l'erreur de marche aléatoire d'un gyroscope à fibres optiques peut être réduite par l'utilisation d'un signal lumineux non polarisé au cours du processus. La dépolarisation d'onde lumineuse modulée par la bobine de détection à fibres optiques ou la combinaison de celle-ci avec l'onde lumineuse non modulée de polarisation orthogonale permet d'obtenir une réduction de 3 db du RIN. |
