Performance improvements in depolarized fiber gyros

Bogdan Szafraniec; John R. Feth; Ralph A. Bergh; James N. Blake

We describe amplitude-type polarization errors in depolarized fiber gyros and show a management scheme for their suppression. Prototypes operating both at 0.8 micrometers and 1.3 micrometers wavelengths exhibiting navigation grade drift and noise performance have been realized.
