Abstract
Polarization modulation errors in all-fiber depolarized gyros having imperfect depolarization are examined. As in the case of PM fiber gyros, birefringence modulation is shown to give rise to quadrature errors. In addition, we demonstrate the existence of a small time lag between the modulation of the two linear polarization states of a fiber-wound PZT modulator by correlating this effect with an associated signal channel error. Proper frequency operation and/or good depolarization of the light act to reduce both types of errors.Keywords
